I am sure everything I am about to ask has somewhere been covered. I can also assure you I did my due diligence in attempting to self help by searching on my own. With that in mind, if your answer is gonna be rude, can you please work some useful info into the insult.
87 accord (A20A1) 2.0 (carb.)
Sheared a number of teeth below crank on timing belt at 10-15 mph in neautral at a coast. I did try to start it a couple times, as the timing belt appeared intact on cam pulley. Inspected valves from top side. No obvious issues... New belt on. Things seemed fine. Process involved cutting away timing belt lower cover.
6 months later... 90 mile round trip drive, car ran fine at start.... Became will I make it home by the end. Compression test showed 130-0-0-115. No water in oil, no gas in oil, exaust seemed as usual, except some cold start smoking had started after T. Belt issue. Car would start to run warm at times, with full coolant. I would also hear what sounded like a massive air pocket go through heater core, at times, and realized it would cool back to normal temp. after that happened. Im thinking valves, but also maybe head gasket. Its my only vehicle so have to drive it during this time. Hear water pump bearring failing. Day before I i tend to replace it fails, and pulley breaks away from pump.... Alternator belt now being free and bored decides its gonna do a little dance, and make a little love with the (i know.. I know) open timing belt. This happens at 60, and I know I am not just slapping a belt on this time.
Tear down results..
Blown head gasket between 2 dead cylcinders, almost every valve is bent to some degree, and multiple cracks between spark plug holes, and valves.
Grab a head from wrecking yard of car with with timing belt and head gasket intact. To machine shop for inspection. Valves all good, .008 out of flat. Have it surfaced, change out the valve seals since I had em and put it all back together.
I was by the book on tightening pattern and steps for intake to head out of car, then installed as 1. Again by the book on head tightening sequence and such. All vacuum lines clearly marked and returned proper. Carb gasket installed meticulously.... And now massive vacuum leak. Car wont even idle. Starting fluid seems to react around base of carb. Pull carb, replace gaskets, reinstall.... Still major vacuum leak. There are 2 very short vacuum lines that go from the metal vacuum tubes (one from each side of motor,) to a dual nipple location on the end of a short pipe that goes into the back of the intake below the carb. I didnt see this pipe until it was out of intake during removal. It doesn't appear broken, but I have a hard time believing it is just stuffed into intake. Is this supposed to be part of the intake and I damaged it, or is there some seal that is missing or somewhere inside intake? On the vacuum diagram this piece I speak of is the only one that has its lines represented by dotted lines... And it is in the 4 o'clock position of the note "TO B" in the diagram. If not this connection... Where else should I be looking, or whats the best home test to find this leak? Also on a couple of occasions after searching for this leak, when I start the car it holds a good idle. Within minutes of a test drive it reverts back to dying unless I am on the gas.. constantly feathering it. Timing has also been double checked... as well as valve adjustments.
Also, the lower radiator hose goes to the pipe running along back of head. The heater hoses split off immediately... And then after the motor mount... There is a smaller line that comes out and runs up under intake where there is something that almost looks like a small inline fuel filter.. Then becomes hose again.... Which then goes????? I just cant seem to find its home. The way it bends and such, it seems to want to go to back of intake area somewhere.
I apologize for the length of this post. As I said its my only transportation, and finances are getting rough with car being down for weeks. I have also been told my fathers health is failing at more than an alarming rate. I need to be able to get to him ASAP... Actually... Like yesterday even.
I really need some guidance in these matters, and thank you in advance.
