Great advice there.It only costs like 20-40 bucks and is entirly worth it to know you have a perfectly flat sealing surface.

well i had this done only about 20 miles ago, so i really don't think it's necessary. i think the compression on a brand new engine should be 170 all across or a little closer than that. i went around the gasket and measured with my digital calipers, and it was a little less at the ends

so what is that crap between the cyl and the block ?

also, use 240cc injectors when you're NA, why use 450's !?

fourthgenhatch

the crap between the block and cyl is devcon liquid aluminum.

the only reason i was using the 450's is cause i had to wire for dpfi to mpfi and already had the plugs that worked with the 450's so i decided to wire those in to make it easier. also wanted to make sure they worked. i will be turbo very soon and decided i'd go ahead and get this outta the way.

Hey hotrex, any overheating problems? how about you crx304? Didn't think so.
Any engine will overheat with no coolant in it! Read the whole thread. He had low coolant and a bad leak.

thanks, i hate when people just read the first and last post and make a comment. crx304 says he's been runnin 18psi or so daily w/ no overheating issues. coolant leak owned me, not the aluminum that will actually allow more heat to dissipate into the outer block.

lap the head anyway. overheating could cause it to wrap even when u just had it done 2 minutes ago.

welp the head is back on anyways----, why do i always have to do everything right away and think i know it all? i got it all back together and was tryin to crank it and just threw on the compression tester for ***** and 1 is still readin 150, so i went to bed and said ---- you to my car.

i'm starting to think i fucked up a valve or the valve seats, shoulda just poured some water in my ports while i had the head off. what other tests could i do to find out what could be wrong.

also i'm now not getting spark gotta ---- with that tomorrow. first i'm checkin out the cap and rotor, if they look fine i'm guessing it'd be the ignition module because that has happened twice before on other hondas. last time i took it to autozone and they tested it and the meter said it was fine, but the guy just gave me the new one anyways and it worked right away, 190 dollar part for free woot-woot
