anyone know a shop in the sf bay area that does endlplate lapping? i live in fremont so near there would be preffered. i dont really wanna go through the trouble/risk of sending them to a shop. thanks

 

are they out of spec?

i personally don't recommend lapping them unless they are out of spec and you have no other alternative.

 

well, i havent measured it, but i can catch my fingernail on several of the lines in the iron, that and i want to weld some of the water passages back into being usable and then get them lapped so i can use them. it seems a waste for a whole iron to be thrown away for a few little bits of metal being missing ( link here: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/engine-teardown-pics-471258/ ). my only alternative is to use them for porting practice but i wont need that for a long time.

 

as i and others said dont bother trying to repair them, yes it is a waste and i was reluctant to toss about 6 irons in the garbage last week but it is what needs to be done.

 

fixing the coolant lands is easy...

do a search...i did a small writeup and posted a few pics on it.

 

post a link, im lazy...

i've seen people try but i wouldn't trust the methods i've seen in a customers car or even my own rebuild.

 

i'm too lazy to find it too .. it was like sometime last year i think.

i'll let you know if i come across it.
