94 ls-r

I have a built ls vtec and there is white oil in the oil fill cap and the driver side of head on valve cover. There is a tiny bit on passenger side of head on the cam rails. The oil in the crank case looks fine. Its a little dirty and due for a change. Coolant is also fine. Runs great and no over heat. This motor has bout 30k on it with the head and block being surfaced and I installed a oem gasket properly. Any ideas?

maybe something wrong with pcv or something. maybe that white stuff is blow by.

im pretty much guessing headgasket, i had that same problem, its a milky white yellow looking ****. definetely check that

obd2 engine block. It has not breather and I only have the hose to the intake. Anyone else hear of this? It does make sense since the location of the milky spots!

The oil in the pan is clean of any water. There is only white built up kinda thick in certain spots. The cam rails look good except for the driver side end also? Why would it only be in 2 spots? It looks like lithium grease on the vc on the driver side only

Someone told me it could be condensation cause it been in the thirties here but not sure. It has not used any coolant

If you coolant level is not dropping then it is condensation. Which is normal. If you are burning coolant there should be more and more of that milky stuff the longer you drive it.

Mr. EG

Are you using an external breather like a catchcan, hopefully considering you have this "built motor".

Actually no. Used to have one but smashed in wreck. I hardly get on it much anymore. Can that cause the white paste in 2 spots? If it was a head gaskett I would think it would be all over?

I gonna have my friend who knows a little more than me look at it. Then clean it up and do an oil change.

94 ls-r

Friend says it look like condenstaion. Gonna wipe it clean tomorrow and change oil. Just keep eye on it I guess

94 ls-r

Can I run half qaurt of atf to clean the motor. Its really clean but wanna flush it out good before clean oil

Mr. EG

No don't do that.

94 ls-r

Any reason? Done it on old truck. Just curious why you cant do it on a honda.

wait, did I read correctly that you have NO PCV system at all?? No PCV valve in the valve cover or in a black box on the back side of the block??

hatmanafro

^if thats true. then theres your problem.

Have the breather hose out of valve cover. The block is obd2. I had to ref a while back so i never put on a aftermarket breather. How can I keep it looking some what stock?

Sounds to me like you have no functioning PCV system. OBD2 LS engines had the PCV valve on the valve cover, while OBD1's had it in a breather box on the block.

This topic recommends you use a 90-95 OBD1 LS block when you do an LS/VTEC build (scroll down to where it shows the pic of the breather box), for the reason of having the PCV system in a box built onto the rear of the block. If you use an OBD2 block, you need to run an aftermarket catch can with PCV valve. Without a PCV system you will have problems with blowby vapors, condensation and other crap, and possibly blow out gaskets and seals.

And there you have it.

I will get one of those breathers soon as I can. I used to have one on my high comp build but the car was hit and smashed it. Then ref soon as car back together. I never get on it much and baby it alot cause I know I need one. Is there any ones that are better for any reason?
