    Re: Mystery Oil Leak

    Cant help with the bolts.

    I think we got that same make your own O ring kit at work and it seems to work really well. if it doesnt Im sure we can get you that O ring here stateside and swim it over.


    Careful with the coolant pipe that runs accross the back of the motor its not available and I havent see any one make anykind of replacement. maybe cleaned the outside up and paint it.

    Clean clean clean what you can and try and paint what you can even in the cold and all.

    Re: Mystery Oil Leak

    you've got me thinking now... i could take the base back off and clean up the area as you say. What do you mean by clean up, is there a method you would use? I noticed lots of small bit of rust on all sorts of different bits round there, components and body bits, nothing severe but maybe i should make this job even bigger and really future proof, I've never done this before though so am open to guidance.

    As for the pipe in particular, I do actually have another by chance, will keep ahold of it.

    Thanks blue.

    Re: Mystery Oil Leak

    Sandpaper,scotch brite and elbow grease. If you have air tools even better. Anyway you can get rid of rust so it doesnt spread is a good thing.

    de grease, primer and paint. I know its cold where your at but if you keep spray cans at room temperature and then take them outside and use them that will help paint stick and dry pretty well. We have Rustolum brand paint in cans for metal you brush on its pretty good.

    All out remove all the parts and get them sandblasted and powder coated.


    EDIT: also I cant remember if I wrote this but here stateside our cars dont have that oil cooler/warmer thing so if it starts giving you a fit you could pitch it I would think. Cool little item anyway.

    Re: Mystery Oil Leak

    Miatas have the same kind of oil warmer, it is tradition to bypass the throttle body coolant and oil warmer when you do cooling mods on those cars, so that is what I did this weekend. Yeah... feel free to pitch that thing.

    Re: Mystery Oil Leak

    Alright big job just got even bigger, got some paint and sandpaper on the way so gonna clean up all the bits I didnt like the look of down there, especially that pipe. Any tips I should know before taking that pipe out?

    Will keep the warmer on for the meantime unless it gives me more problems.

    Cheers.

    Re: Mystery Oil Leak

    Im not sure I would disturb it just clean it up on car best you can and anything else you can under there. I think how it seals to the water pump housing could be really weak.

    Re: Mystery Oil Leak

    Yeah, best not to mess with the coolant pipe. It's really thin metal right where it connects to the water pump housing. After 30 years and neglected coolant flushes, there's not much metal left. Even if it leaks, I'd say smear around the outside of it with RTV. That's what I've done with mine.

    Re: Mystery Oil Leak

    Got the oil filter base on and started on cleaning up the engine block for the new gasket and pan to go on. Took me a while getting the stuck gasket & sealant off. 2 questions I got:

    Is it clean enough? I recorded what it looks like here:
    Shared album - theo jones - Google Photos

    How much sealant am I putting on? everywhere I've read says only a little on the corners, yet from what it looks like theres a decent bit more than that on there originally:
    Shared album - theo jones - Google Photos

    tomorrow is the big day! let me know if you got any other tips for the oil pan, gonna hold the gasket on with some mini zip ties I got like your sewing thread trick blue.

    Cheers.

    All looks good to me.

    The thread trick is so you can put bolts in the holes that have been thread in them and pull it out before you tighten everything up.

    Re: Mystery Oil Leak

    What do you think about the quantity of sealant? really unsure if any at all vs. a little in the corners vs spread thinly but along curved sections etc. ... both sides too?

    Also, im unsure what to torque to, so far I got
    7 ft-lbs = 9.5 Nm
    10 ft-lbs = 13.5 Nm

    I have a torque wrench and wont be going tight tight. gonna tighten bolts in x pattern from inside out too.

    would be nice if the shop manual had a page on this!

    Re: Mystery Oil Leak

    you know, it doesn't matter, the ATP pan I got has a catastrophic positioning problem for the pipe that goes into it, about 5 mm closer to the centre, now means it wont fit between the gap in the baffle plate, and even if it did it would then likely collide with the crank. if you can't tell im pretty pissed off, been going at this job for 2 months for this to finally crop up..

    Re: Mystery Oil Leak

    That's weird it won't fit. Mine was a Spectra...I think and it wasn't made well it needed to be spread some for the front and rear bolt holes to line up.

    The PVC pipe is the worse part of that job getting it slide on while pushing the pan on.

    Now on the EFI models they do have a windage tray on the crank maybe the carbs dont.

    Torque 10 ft lbs sounds OK most torque wrenches aren't acurate at that low.

    Sealant I just do the parts where the round meets the flat on the ends of of the pan.

    Re: Mystery Oil Leak

    Ok calmed down and investigated, the PVC pipe seems to be ~10mm closer to centre than the pan I've got, otherwise they match pretty well.

    on the rockauto website the compatibility is with carbs & EFI, may be wrong but I'd hope that would be accurate. I'm worried its because I have an A20A4 and that may be different to US spec, I remember the part numbers were different by one number, gonna call Honda to check on Monday. (they dont have it in stock annoyingly)

    I'm considering removing that baffle plate and cutting room in it for the pipe, just unsure if the pipe would be too close to the crank and/or anything else moving. I've got some photos of crank lineup and the pan compared to the old one, so will study those: Shared album - theo jones - Google Photos

    Have any of you got an old stock pan lying around you can measure for me? I'm keen to see the distance of the pipe to the outside, if its the same as my old one (UK spec) or the same as the new one.

    Big job... just got bigger...

    edit: From the photos I took, I have the PCV pipe positioning to be approximately 2mm closer to the centre than the baffle cutout actually allows, need to figure out if this in line with anything spinning, and then may try bending the pipe and/or cutting the baffle plate to allow this. if it's too edgy gonna have to buy another one.

    Honestly I dont see any issue with notching the pan or cutting a lot off the pcv pipe on the inside

    I think I would mess with the pipe before the windage tray but I dont think it matter much.

    Like you said make sure it doesnt hit the crank is all.

    Re: Mystery Oil Leak

    Yeah, just make it work. All that pipe does is dribble oil back into the pan.

    I know what you mean though. It seems like any time I buy parts from Rock Auto, the job always turns into a big nightmare.

    Re: Mystery Oil Leak

    Okay, nice one thanks for that guys, wasnt sure how much pressure it carried, but confident to give it a good bend now, failing that, chop it off. Will let you know how I get on.

    Re: Mystery Oil Leak

    bought an angle grinder at toolstation and got cracking.

    Plan A to precise cut and then bend quickly went out the window, not much precision going on. (this method How to Bend Thick Metal Without Traditional Tools - Kevin Caron - YouTube)

    Plan B to chop the whole inner section of the pipe off went a treat though.

    very ghetto daisy chaining power cords out the porch but it worked and my neighbours didnt seem too fussed.

    Re: Mystery Oil Leak

    Hey,

    so managed to get new pan on today, ended up ziptying gasket to block through the 4 bolt holes which have openings through the top, and hondabonded the 4 corners, both sides of gasket. Then fit pan with PCV hose putting up a struggle, still cant get it to slide all the way up. Torqued in X pattern to 9.5 Nm.

    I got questions on fitment though, there's a couple areas where the gasket protrudes slightly and others where it doesn't, see the vid here:
    Google Photos

    Also on the transmission side I can see it's not rolled over completley however there is a millimetre gap between pan and gasket which wouldnt be there in an ideal world. see vid here: Google Photos

    Are either of these reasons to loosen it and rejig it? obviously I dont want to have to redo this job but its such a pain getting it to all line up in position.

    Shared album - theo jones - Google Photos

    Cheers.

    edit: i loosened and retorqued the bolts and it seems pretty well seated. I torqued them X pattern, then went round again a little (the central ones could be torqued again) but tbh dont think im gonna go higher than 9.5Nm as it already feels quite tight.

    Re: Mystery Oil Leak

    My google is messing with the picture upload....but with gaskets you can always go a little tighter later on but backing it off after over tightening never seems to work. Sounds like your got it pretty light torque and it should be OK. if it leaks later you can go a little more.

    Re: Mystery Oil Leak

    Got it all back together, oil in, coolant in, turned the key, nothing.

    I'd blown the battery fuse when removing the alternator, I even remember seeing it spark. Nice little reminder to always take off your battery negative before touching the electrics.

    Will hopefully get new fuse on Monday.
