OK, so put in my oem rebuilt GSR bottom end about 2 weeks ago. It was a light hone with new bearings and rings. The head has been used on several differnt motors without a resurface. But did recently have valve stem seals replaced. Used a new waterpump and timing belt. Its a b16 head with GSR cams. So the problems im having is the car is smoking under deceleration and a little at WOT. And then VTEC isnt coming sometimes which i attribute to not enough oil pressure cause when i filled the oil about half a quart over, it worked fine. But also tonight it started leaking coolant from the front driverside of the block at the oil pan that looks like its coming from the waterpump, but its milky white, which is a sign of oil in the coolant. So i drained about 1 quart of oil and the oil is fine, no signs of coolant in the oil. And its leaking oil from between the head and block under the dizzy. So would this be a sign of a warped head. The head has never been overheated. Gimme feedback ASAP please. Thanks in advance and sorry its so long.

Oh, and compression test is showing 200 across the board and my gauge reads about 5psi low. The car when vtec comes in and at 7lbs of boost feels awesome, Very strong.

leak down

a1320honda

well i went ahead and pulled the head off and there was oil sitting on top of all four pistons. NOt alot but enough. So before i put the GSR head on it, i filled all four cylinders with oil and gonna let em sit overnight and see if they lose any oil. If the drop oil, does that mean i need to redo the rings?

That's a very interesting style of leak down test.....

If your smoking at wot and on decel, it's pretty clear you have likely have a ring leakage issue. The low oil pressure is also another bad sign.... Either way, it sounds like the clock is ticking.

a1320honda

i dont understand why it would be rings though, i just reringed it about 105 miles ago. I had this head on my LS/VTEC and it was smoking almost the exact same way, just its not as bad now because on the LS bottom end, i blew the ringlands in #3. I really think its a head problem considering like i said, the head hasnt been milled and its been on about 5 different motor in the past 3 years. In theory the oil in the cylinders would work wouldnt it? Especialy if i left it over several hours? Or is that not a reliable way to check for bad rings?

i think ur head is warped take a straight edge and plance it on ur head and u wil find out

philafelman

u should have done a leakdown before you pulled the head...if youve spent all that time and money on the engine, just take the head and get it resurfaced. might wanna get an oil press. gauge on there too, have you replaced the oil pump?

also, are you torquing the head down correctly?

RC000E

I agree, if you feel strongly the head is the issue, then have it milled. Did you put a straight edge across the head at various angles since you have it off?

When you pulled the head did you see evidence of the gasket allowing oil to enter the chamber/s? Smoke on decel and wot is generally always rings, but if the headgasket was allowing oil to pass into the chamber, then under decel it basically isn't burning it off, and under wot a small amount of blowby could be pushing oil into the chamber via whatever leak exists.

Good luck with your issue.

the oil on the pistons could be from removeing the head, the oil in the head drained when you pulled the head off, if your coolant is milky then you are deff. getting oil mixing some where. does your turbo have coolant lines running to it also because your seals could be leaking.

a1320honda

charge pipes are bone dry. intake plenum is clean and theres no oil being passed by the turbo. i just figures since there was oil in the coolant, that wasnt really goin to be a ring problem. and ya i know i should have done a leakdown test, but i dont know anyone with a tester and i couldnt afford to buy one right now. So it is what it is lol. the GSR head i have had never beenoff its oem block until we pulled so i have a feeling its gonna be in good shape.

take a picture of the head gasket and the under side of the head and post it please.

D@nnY

did you look at the valve stems to see if they are leaking oil into the cylinders? did you use a new headgasket? the block may be whats warped also...get a straight edge and some feeler gauges

a1320honda

I replaced the valve stem seals less than 2000 miles ago. Yes it was a new headgasket, and the block only has about 90k on it and was never beat on, the only reason it came out of the car is cause it was totaled and the head was sold off.

This is the side that touches the block:

And the side on the head

alright, sorry to hassle you but it helps us think, pic of the motor with the head off?

a1320honda

The cylinders are filled with oil, but here ya go

philafelman

in ur first post you said the head has been used on several motors, and a couple posts ago, you said it was used on one motor...which is it? what are you using for head studs?

should of checked if the head was warped before putting it on.

drain all the oil. if coolant is in the oil pan its going to be sitting on top of the oil and will come out last.

I dont recall saying it was used on just one motor. but no, its been on several motors without being resurfaced. And as far as headstuds....ARP TQ'd to 68ft/lbs in 3 steps 22, 45, and 68.

a1320honda

so i put oil in all four cylinders and let em sit for 24 hours and and no oil seeped past the rings, if it did it wasnt a noticeable amount. So i thought id try gas since its alot thinner. So pretty much if theres any gas in em when i wake up in the morning id be pretty happy.

philafelman

will gas evaporate if left exposed?

yes its a volatile hydrocarbon, hence it burns well.

kyden

did you ever have the head checked for straightness?

EARLdaSQUIRREL

i cant imagine letting gas sit in the cylinders and going down into your bearings being a good idea
