Just got horrible news from Blackstone...Mysterious Coolant Consumption...continued- -> - LI-S4 2006-04-27 11:44:29 (490 views)

Same Problem - Hibiscus Red S4 2006-04-27 15:10:55 (138 views)

Well then you make five of us having the same problem... - LI-S4 2006-04-27 16:03:19 (65 views)

wecome to our familiy - S4 AVT 2006-04-27 21:16:53 (40 views)

:-( - Hibiscus Red S4 2006-04-28 09:37:50 (60 views)

This is getting strange. I lose coolant, too, and I can't tell where it's leaking from - StoneMan 2006-04-28 10:25:23 (89 views)

You have a smell... that's a GOOD sign. - Mike2kS4@ASP 2006-04-28 10:31:04 (81 views)

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 (82 views)

Yes...that was the first place we looked- -> - LI-S4 2006-04-27 16:02:54 (78 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 (43 views)

Sorry didnt read the earlier thread, sounds like a good diagnosis. - Killer00S4 2006-04-27 20:16:31 (36 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 (83 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 (55 views)

Good to know. Unless I need an excuse to buy Revolvers :-) - StoneMan 2006-04-27 13:18:13 (41 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 (70 views)

repost, bish :p - mjtaylor 2006-04-27 12:38:54 (48 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 (36 views)

the cam bearings are actually just part of the head - no bearing inserts or anything. - mjtaylor 2006-04-28 07:32:18 (97 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 (126 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 (109 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 (72 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 (124 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 (29 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 (31 views)

i have the sprockets and bolts for you, along with a few other random accessories - mjtaylor 2006-04-28 13:35:45 (25 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 (46 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 (39 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 (45 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 (50 views)

We scoured the car... - LI-S4 2006-04-27 12:34:32 (83 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 (53 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 (52 views)

That's good news... - LI-S4 2006-04-27 11:55:04 (61 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 (44 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 (101 views)

main sources of wear i can think of are piston skirts and cam bearings - mjtaylor 2006-04-27 11:57:23 (47 views)

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

2nd! - dscottjr 2006-04-27 11:58:58 (61 views)
