300 000 + Kms Tune Up

[JFreddy]

Ok, a few quick questions and looking for input before I start.

I have an oil sweat that seems like a rear main (crank seal) that is starting to go. So this winter I plan on changing:
Timing Belt
Crank Seal
& Port +Polish cylinder head

anyways while I have the transmission off are there any other seals I should replace? and while doing timing belt should I replace anything else?

My clutch and water pump, alternator have recently been changed.
And with the cylinder head off, what consists of a rebuild kit? pistons... rings... and???

Thanks for all your help
and FYI 89 Accord Ex-i (Fuel Injected) with bolt ons.

if you want you can rebuild the whole engine....you will have to take it out so you can send it to a shop.

i would take the head to a shop and get like a 3 angle valve grind

ok, sounds good but still I wanna know what consists of a rebuild... and still no answer on any of the seals?

Drive axle seals other than that unles the fifth gear cover is leaking.

if you want to rebuild. get new piston rings. keep the stock pistons. they are probably in good shape, just make sure you clean the areas where rings are seat.
main bearings and bunch of small gaskets and o-rings.
The best way to do is tear it apart and start from the bottom.
