oil change

[jj2gdsm]

Would the need for an oil change cause my car to smoke white on start up till i heat up .Also was rebulid about 8k ago.

No. Look at your valve stems leaking.

Well white smoke is coolant burning... Are you positive it's white or is it a blueish color?

 

[jj2gdsm]

It white and im not losing coolant fast or anything seems pretty regual .I add water/coolant about every other week .I do notice some oil loss but not much plus it really white like steam.

 

[LiquidX]

Unless you over heat or get hot enough to boil your coolant, you shouldn't be loosing any. It's a closed system until pressure builds up enough to overcome the cap pressure and travel to the over flow tank.

Any signs of the oil having coolant in it? Have you done a leak down test yet?

 

[Guzman08]

what did u rebuild it with? what gaskets did u use?

 

[jj2gdsm]

fel pro headgasket and thats what i thought too cheap autozone gaskets!I hope its not going out its only been 4 months.

 

[STLskater92]

Get yourself a multi layered metal head gasket. And always try to avoid fail pro and other autozone gaskets

 

[ilco187]

Fel-pro also makes MLS HG's.

 

[jj2gdsm]

So you guys think my head gasket is going out.

 

[94_TSi]

Do a leakdown test, if it is your headgasket get a oem mitsu composite gasket not a multi layer.

 

[96 420a-t]

Synthetic oil Burns more white.

 

[Guzman08]

Is it bad to get a mulitlayer headgasket??

Also i wouldnt say Fel-pro is bad just dont use their head gaskets or valve stems seals unless u plan on just selling the car.

 

[T is for TURBO]

It's most likely the gasket.
How was the head and block prepped before the you replaced the head gasket?
Where the head studs torqued properly?

Also, when WAS the oil changed last?

If you don't plan on modifying the engine, get an OEM gasket.
If you plan on modding, I would suggest an MLS, but if you go MLS, the head and block have to be prepped more thoroughly for it. And if you go with an MLS, I would suggest ARP headstuds.

But do a leak down test as advised above before you tear anything apart.

Is it bad to get a mulitlayer headgasket??

Absolutlely not.

Yes, only if your head and block don't have the proper RA number. MLS gaskets require a mirror shine surface free from imperfections to allow a 100% seal. If you didn't do the surfacing, then it's possible that the minute valleys in the sealing surfaces are allowing pathways to form into the combustion chamber.

This is why composite gaskets (stock) are so viable as they fill in the small imperfections when torqued down.

Also i wouldnt say Fel-pro is bad just dont use their head gaskets or valve stems seals unless u plan on just selling the car.

What's wrong with Fel-Pro? They are one of the leading gasket makers. They have IMO the BEST head gasket and all of their other gaskets are completely fine to use. My rebuild is using Fel-Pro gaskets from
Autozone and not a single leak.

ive read on here that use viton valve seals instead of felpro and to use another head gasket besides the one that comes with the gasket set. im never said they suck i bought the felpro gasket set from advance for 107 but im going to spray them with copper spray just for a better seal..

 

[jj2gdsm]

the last oil change was 4k and what do you mean by preped what do you have to do to the head and block?

As in when you "built" it, were the head and block both resurfaced?

also what brand of valve seals did u use

 

[LiquidX]

ive read on here that use viton valve seals instead of felpro:

Just so you know, Viton is a type of synthetic rubber, not a brand of seals. I'm almost positive felpro uses Viton rubber for their seals.

jj2gdsm, bud. if your head or block is warp, no matter what type of head gaskets you use its gonna be the same results. you are gonna blew the head gaskets and leak coolant.

The problem is not the head gaskets, its the condition of your head and block. CHECK for straightness and make sure its flat before you put any brand of head gaskets on there.

Good Luck.

^ +1 on that. Has anyone had the thought cross their minds that it may be a crack somewhere on the turbo? I believe that would cause smoke in a cold situation and as it heats up the metal expands and seals? Idk just throwing it out as a possibility. It is normal to get some vapors out of a cold motor depending on outside temps.

 

[jj2gdsm]

I also had that thought of a small crack in the turbo that seals when it gets hot .Also both head and block were resufaced.

I second this.

What did they use to resurface? Was it a deck milling machine or a belt sander? Just trying to get some facts straightened out.
