It could be those O-rings on the hardpipes in the valley, leak in one of your soft lines or the hardlines going to the turbos or the turbos themselves.

Thanks Mike. That makes me feel better. I'll have it all apart in due time - StoneMan 2006-04-29 06:31:22 (36 views)

Which valley Mike? - Hibiscus Red S4 2006-04-28 10:36:52 (39 views)

Under your intake manifold. - Mike2kS4@ASP 2006-04-28 11:05:23 (54 views)

Did you look @ the hard coolant lines that are in the valley between the heads? - Killer00S4 2006-04-27 14:56:45 (79 views)

Yes...that was the first place we looked- -> - LI-S4 2006-04-27 16:02:54 (77 views)

And your oil problem might not be related to your coolant issue? - Killer00S4 2006-04-27 16:33:47 (42 views)

I have no doubt they are related...did I give you a different impression? - LI-S4 2006-04-27 17:45:46 (40 views)

Sorry didnt read the earlier thread, sounds like a good diagnosis. - Killer00S4 2006-04-27 20:16:31 (35 views)

It's related. - Mike2kS4@ASP 2006-04-27 16:39:25 (42 views)

I'm NOT an expert on the materials within the 2.7, but my bet is on cam bearings - Verr?ckt 2006-04-27 12:32:29 (82 views)

Are cams/cam bearings a weak point in these motors? - StoneMan 2006-04-27 12:42:23 (53 views)

heard of / seen a couple failures, most or all probably due to external forces - mjtaylor 2006-04-27 12:46:45 (51 views)

yeah when the car jumped off the cliff ;p - lemieux@curbside 2006-04-27 13:24:53 (41 views)

No. - Mike2kS4@ASP 2006-04-27 12:44:33 (54 views)

Good to know. Unless I need an excuse to buy Revolvers :-) - StoneMan 2006-04-27 13:18:13 (40 views)

I am interested in what might be an alumimum wear part..but I am more concerned about.. - LI-S4 2006-04-27 12:41:10 (93 views)

What is your coolant consumption? - reefer_bob 2006-04-27 12:58:27 (50 views)

Head gasket, RMS, oil cooler (more likely will put oil in coolant), turbos... ummm... - Mike2kS4@ASP 2006-04-27 12:44:07 (68 views)

repost, bish :p - mjtaylor 2006-04-27 12:38:54 (47 views)

2nd. Cam-bearings are aluminum. - Mike2kS4@ASP 2006-04-27 12:36:44 (55 views)

Are all the bearings in the engine aluminum? Or just the cam bearings? - System_S4k 2006-04-28 07:26:33 (35 views)

the cam bearings are actually just part of the head - no bearing inserts or anything. - mjtaylor 2006-04-28 07:32:18 (96 views)

Ouchie. Thanks for the info. - System_S4k 2006-04-28 07:36:19 (33 views)

I'm not afraid to expose my ignorance... - LI-S4 2006-04-27 13:48:39 (124 views)

No problem. - Mike2kS4@ASP 2006-04-27 15:24:27 (129 views)

So it sounds to me you'd put your $$ on head gasket... - LI-S4 2006-04-27 15:59:49 (250 views)

I actually am hoping for an RMS... - Mike2kS4@ASP 2006-04-27 16:21:08 (108 views)

Insight needed....why pray for the RMS instead of something I would think simple like head gasket? - LI-S4 2006-04-27 17:53:55 (84 views)

Yes, simplicity. - Mike2kS4@ASP 2006-04-27 18:17:18 (48 views)

hhmmm... that's a surprise. - LI-S4 2006-04-27 18:21:18 (71 views)

How so? - Mike2kS4@ASP 2006-04-27 18:24:23 (78 views)

Re: How so? - LI-S4 2006-04-27 19:02:17 (69 views)

Yea, it's a total pain no matter... - Mike2kS4@ASP 2006-04-27 19:20:26 (76 views)

i doubt the rear main .. the RMS flange has that chanel that would direct an eventual coolant leak - lemieux@curbside 2006-04-28 13:00:15 (123 views)

erf. Darn. - Mike2kS4@ASP 2006-04-28 13:08:37 (53 views)

yep , ygm in 5 - lemieux@curbside 2006-04-28 13:23:29 (28 views)

i'll still buy the old block off you :p - mjtaylor 2006-04-28 13:29:05 (26 views)

oh yeah my friend's old block ;p - lemieux@curbside 2006-04-28 13:30:06 (30 views)

i have the sprockets and bolts for you, along with a few other random accessories - mjtaylor 2006-04-28 13:35:45 (24 views)

please give me a ring next time you plan on going to ASP . - lemieux@curbside 2006-05-01 07:32:37 (30 views)

sure will, i'll probably head over in a week or so to drop some stuff off. - mjtaylor 2006-05-01 07:38:32 (37 views)

each cam has 1 mark .. not each cyl iirc. - lemieux@curbside 2006-05-01 07:41:53 (45 views)

oh.. thats just to time the cams properly - i thought you wanted to get each cyl to TDC for a - mjtaylor 2006-05-01 07:49:29 (37 views)

..figure out TCD for each head .. just theoretically - lemieux@curbside 2006-05-01 07:52:44 (37 views)

I'd just set the crank to TDC and see where things line up - then use that as a reference. - mjtaylor 2006-05-01 08:03:58 (33 views)

And your FATS time is equally far from my ability to comprehend!!! - LI-S4 2006-04-28 07:24:44 (37 views)

Before pulling the engine, you could also do a leak down test to check the head gasket... - reefer_bob 2006-04-27 15:49:47 (44 views)

Well, the gasket can leak between oil and water passages but not the cylinder itself... - Mike2kS4@ASP 2006-04-27 16:14:49 (76 views)

yup - this should be pretty apparent from the condition of the gasket when you pull it - mjtaylor 2006-04-27 17:39:15 (38 views)

I talked with dealer mech and they said the worst situation will be - S4 AVT 2006-04-27 15:17:38 (87 views)

did your mechanic ever check the turbo coolant lines?? - L0rd of the Rings 2006-04-27 12:11:27 (49 views)

We scoured the car... - LI-S4 2006-04-27 12:34:32 (82 views)

I will call you in a bit. - ECD212 2006-04-27 12:10:39 (48 views)

Why am I getting scared.. - S4 AVT 2006-04-27 12:01:00 (65 views)

just think what the extra cylinder pressures from stage 3 will do to an already compromised seal... - mjtaylor 2006-04-27 12:02:15 (104 views)

: ) hey thanks you and Alex always help me a lot in this forum.. even you guys hate me lol! - S4 AVT 2006-04-27 12:05:18 (50 views)

This is why it's a good idea to have oil analyzed - glad they notified you of a problem - O.W. Kenobi 2006-04-27 11:55:05 (100 views)

i dont believe the bearings are aluminum, theyre pretty damned heavy - mjtaylor 2006-04-27 11:49:53 (51 views)

That's good news... - LI-S4 2006-04-27 11:55:04 (60 views)

what was the coolant level as in % in the oil sample ? - lemieux@curbside 2006-04-27 12:44:56 (46 views)

Should be 3 ppm...registered 41 ppm - LI-S4 2006-04-27 13:05:22 (43 views)

it doesn't make sense .. at the bottom it shows the % ..antifreeze should be 0% and you have .. % - lemieux@curbside 2006-04-27 13:20:41 (100 views)

main sources of wear i can think of are piston skirts and cam bearings - mjtaylor 2006-04-27 11:57:23 (46 views)

Blown headgasket. - S4KTS 2006-04-27 11:45:37 (92 views)
