hey everyone ive got a 2000 prelude sh with a jrsc setup running the 9psi pulley. mods are 450cc injectors i/h/e and it was tuned on hondata s300. I swapped on a red valve cover on that came from my cousins old cursed prelude haha and my dipstick kept shooting out. eventually i blew out my front a rear main seal. so i reverted back to my old valve cover after being painted red. the blowby valve was clogged on the cursed VC. well i took it to a shop to replace the front and rear. and instantly blew out the seals again once driven. i took it back to the shop ad told the tech to make sure they weren't leaking after he did it again. he blew them out again too. hes doing a compression check but i had it checked a month ago and it was 185 185 185 185. which is pretty normal. and the pcv seems to be fine as well. im begining to be stumped and so is the tech working on the car. my car has been down since the first week of november and its now feb 15th. its killing me not do drive it. any help would be greatly appreciated. sorry for the messy post

 

. . . sound like you have a bunch of blow by. I had a problem with cam seals once. but it was because the felpro ones from autozone were the wrong size. Got some from honda and haven't had a problem since.

 

yea i know its a blow by issue but what would i do to stop it from being a big deal?

 

more crankcase ventilation. Get a couple fittings welded on the VC and run them to a breather tank. B&R Fittings makes a nice kit

 

^^^ x2

Now when you say front and rear main seals "blew out" - what exactly do you mean? They didn't properly seal and you have oil leaking from between the tranny/block and on the opposite side as well?

even though this is a JRSC 'lude, I don't know why it was moved to forced induction when it's involving just oil issues and not the JRSC o_O'

 

yes leaking oil from between block and tranny and same on the opposite side. and idk why it got moves either haha. oh and i forgot to mention the car only has 73k orig on it

 

if you have that much blow by, you have an issue. how much timing is it running in boost? do you have access to a bore scope to look at the pistons? We just had a JRSC type-r swapped car come in, made really low numbers, the pistons are broke, you can see the top of the rings in spots, and it still doesnt push the seals out

 

pistons are fine. did a comp test and yes on seeing them too. im getting alot of crank pressure because my VC isnt able to release enough pressure fast enough. something in the pcv is colgged so looks like im going to do this http://i31.photobucket.com/albums/c4...d/DSCF1644.jpg
