Ok I have never assembled an engine and I am doing mine this Saturday. What things do I really need to watch out for. Are there any tricks that I should know that the Workshop manual doesnt cover. After It's assembled how can I do a compression test before I install the engine. Or do I just need to knock on wood and still it back together? For those who dont know its a 13b-rew but I belive the Fc and Fd blocks are the same right?

clearance the seals first, that takes the longest

Ok what exactly do you mean Mike, rember I have never actually assembled an engine so pretend that I dont know what clearancing the seals means.

ok take your clean rotors and fit all the seals to each groove in the rotor. the side seals come a tad long, so you need to sand em to length, so you fit all the seals to each groove, then you can assemble the engine. the seal clearancing takes awhile, its not really something you can do while you are actually putting the case together. another thing is to put a little motor oil on all the sealing surfaces, the rotor housings really soak it up

Yeah measure everything twice, thats where good compression\long life comes from.



I thought Ray was gonna help you?

Ok so just dry fit it all together first. No problem. Thanks.

on the RE Amemiya FC vid, they used a small bench grinder for the side seals.

good luck man!
