Well, the oil had to be going somewhere

[AudiA4_20T]

This could be a blessing in disguise... its possible that my rings are gapped fine and my HG was just slowly going to shit... I had been spinning my car to like 7k haha but whatever I was going to put some new rod bearings in there and maybe Ill get a few new sets of rings

[vdubstreets]

looking at your other thread i was thinking to myself did he check his coolant?

[AudiA4_20T]

I had seen a small bit but shrugged it off at first... Not sure if the the rings are gapped right or the HG has been bad the whole time...

[ILoveT]

At least you're not angry. I would have kicked my door in.

lol realistically a headgasket is like $20

[Das General]

"7 Grand!"

Are we gonna pull your motor too?

[CO AVANT]

still sucks you got to go through the motions of getting it all right again after not too many miles on it. At least yours didn't grenade like mine did I'm sure you will get her all fixed in no time Clint.

[wolfdog]

Clint! You CAN take close up pictures!

My coolant reservoir looks like crap but it gets lower, not higher so with any luck it's just the flange (or oil cooler). We will have to flush it, too.

2002 A4 FTW!

is yours milky? if not its probably the oil cooler

Derek I think the 7 grand pulls did me in!

7 grand! lol. I'm a poser.

Find a way to blame it on Reilly.

[dirtybrd]

I know VW used to have a problem with the oil coolers cracking and leaking coolant into the oil. I'd try that first, flush it and put just water to see if that will fix it.

lol been there done that I wrote the writeup for it Chris... I think we have a bigger problem on our hands. O well I needed better rod bearings anyway lol

[Das General]

You think that gave you the rod knock

[317ssayzarc]

you got an oil pressure gauge on that bish clint? also, if the headgasket was leaking that bad youd notice tons of smoke lol

[AudiA4_20T]

no OP gauge, heres the catch... Its been eating Id say a quart every 500 miles or so maybe more maybe less. Car ran like a champ and whatever, but I would spin it to like 7200ish at least once a week. I have to do new rod bearings anyway so I guess this isnt so bad

[Elliott]

Just for future reference, how hard is the HG job on a 1.8?

my motor has a faint knocking sound, it partially goes away when the car warms up so im thinking piston slap... i set my wall to skirt at .003 and thats pretty tight as far as aftermarket pistons are concerned... i rev it out to 7700 and oil pressures stayed at 30 at idle since the first startup, so i dont think its bearings... im start to give up on this car

[Das General]

Clint, when I was driving behind you one day in the red monster, I did notice a little bit of smoke coming from your exhaust...but I would hardly say you were burning oil.

It definitely does that when he gets on the gas. It didn't happen much on the way to Doug's cookout, just when he got on it a bit. I think that also happened before he went 2.0, when I followed him to the DJD GTG last year.

[dougyfresh]

I'd say the easiest way is to disconnect the turbo inlet and downpipe. Disconnect the throttle body charge line. Then pull the valve cover off. Then set the engine to TDC on cylinder #1 (for TB realignment). Then unbolt the head bolts. Then remove the coolant lines and other misc stuff. Then pull the head off with both the intake and exhaust manifolds intact. Replace gasket and reattach everything.



Clint.
You're oil cooler is still holding strong? Even after you replaced it pre-2.0 build?

The car ran fine when I drove it the other weekend. Dare I say I took it up near 7k in 2nd gear once or twice ??? That damn K03 kept making me ask "When? When? When will it kick in?" haha. I did like the long gears of that 2.8 trans and the suspension work you have done.



PS. The AVant might come back to life sooner than I thought...

Doug, sounds good about the Avant. You noticed that the K03 doesnt die out like a normal one right? Its odd I dont know why that is the car doesnt really die out but whatever, I cant wait for some serious lag

And also, Ill be taking some pics when I do the HG

[AudiA4_20T]

Question... does revving to high cause blown HGs?

[317ssayzarc]

no, super high cylinder pressure does (could be caused by many things) provided the mating surfaces were good and the head was torqued down

[AudiA4_20T]

I heard heat does it also... that would explain everything cause I busted a coolant line and pegged my needle to the hot twice by mistake

[317ssayzarc]

yup, that could warp the mating surfaces

[CO AVANT]

Are you not keeping an eye on your coolant, egt, etc temps on vag?

Take a flashlight and look down your sparkplug holes with the plugs taken out and tell me what the top of the pistons look like. or post pics.


BTW, headgasket job is like taking out half the motor, minus the shitty bellhousing bolts thank god...

[sean1.8t]

lol realistically a headgasket is like $20

plus new stretch bolts. and valve cover gasket. and a decent amount of time all while making sure your timing doesn't get knocked off..

but looks like you were already going to be in rome, so enjoy the stay i say

[Don Supreme]

For the record 7000 RPM is not high!

[A4ringedONE8T]

Another built motor coming back apart ... big surprise!

lol I still give myself tons of credit

Jordan, is it possible I toasted my pistons? What happened was like 3 days before school ended I blew this coolant hose (I called u that day) and I tightened her up but it never fixed it. So I kept putting in distilled water (it was a slow leak) just to get home because there was no one to help me at school. 1/2 way home it ran out again and I filled it. But thats the only thing that happened

[CO AVANT]

possible but I think your problem lies elsewhere. Have any metal shavings come out of the oil when it was drained last? When your rear coolant hose went, did you drive around until the coolant light came on? Was there 0 coolant in the reserviour when you stopped to inspect it? If so you engine was HOT AS SHIT. This is not good and can warp the cylinders, blow a head gasket, etc, etc.

[dirtybrd]

I still think you have a cooler issue. If the head was warped or the gasket was blown you would for sure have some drivability issues.

[CO AVANT]

I feel he did his piston clearances too tight. I would go 4/1000's. For Clint's sake I hope it's as simple as a new oil cooler. That would be an easy fix compared to having to take off the head again. I would still like you to inspect down the spark plug holes though. I'd spend some time on it soon. Take off the cooler and inspect for mixing at that point. You might be able to reuse that gasket/flange if you don't damage it.

[Don Supreme]

Did it over heat when you had the coolant issue?

[AudiA4_20T]

Did it over heat when you had the coolant issue?

yes there was not much I could do... I was in traffic

[Mikef5000]

It is very likely you warped you head. Normally I'd say you'd have drivability issues and smoke... but there's exceptions to everything.

the car ran great... Would it warp my pistons and block also? or just the head? And what part of the head would it warp? could I just get it machined flat again?

[317ssayzarc]

No to the pistons, very unlikely to the block and the head may be savable depending on how much its warped
