Contour Enthusiasts Group Archives Forums Modifications Forced Induction Crap

I was thinking about this last night while scrambling to finish my car:

How can your valve cover tubes be blowing off? I ask, because in theory, even if there is pressure under the valve covers, the vacuum from the intake BEFORE the turbo (where the hoses from the valve covers should be plummed too) SHOULD provide enough suction to evacuate the pressure under the valve covers, so much so, that they wouldn't build up enough pressure to blow off. That's what doesn't make sense. I want to say he has something all f'ed up with the plumbing (taking a stab here).

Once, when I first had the turbo 2.5, I thought I'd try routing the valve cover vents into the system, but I screwed up and plummed my valve covers into the pressurized side of the intake and the car ran at first and then after a while it BARELY ran - it was misfirely blowing smoke and seem like it was ready to die. What I was doing was pusing oil up past the rings into the combustion chamber due to my FUBAR.

Before you say to hell with it, can you please post a series of photos showing the route from each valve cover tube - to where it enters your intake tract?

No kidding. Does seem awfully strange to just say fugg it. All of this time and money. Why would all these new parts just sh!t the bed?

It's hard to argue with 25psi on the front bank being a plumbing problem.

I haven't posted everything that I've tried before throwing in the towel.

What happend:
I was driving the car for hours trying different things and giving them time to see if they'd take.
1. I dropped the cat back, replumbed the PCV into the intake, capped off the nipple on the intake pipe (between the MAF and turbo) while leaving the valve cover vents tapped into the intake
Results: Smoked non-stop, boost was reading very high and it wouldn't idle without dying. To start the MOFO, I had to floor it and it would sputter to life. Even the actual cranking sounded different. Rather than a consisent cranking, it sounded like atleast a couple of cylinders had no compression and weren't putting out resistance while cranking over. Once it got to operating temps, it ran like s$*% and wanted to die. WOT runs would shoot the front valve cover vent off at the OEM connector and a nitrous like purge spray out of my vented hood would shoot up Keeping the car running by actuating the TB by hand while having the hood popped, I opened up the oil cap and it'd hiss from the pressure change and puff smoke at a high rate.

2. I let the car cool down. I bypassed the intake tube's 2 nipples to seal the intake up. I vented the valve cover vents to atmosphere, leaving the tubes inplace but disconnected from it's oil seperator.
NOTHING changed. The I.D. of the OEM valve cover vent was enough resistance to do the exact samething under a WOT run.

This is when I did the 2nd compression test only to find what I had. I'm just pissed off about having a bogus compression test that got my hopes up enough to dump another $750 into this car.

This isn't a sudden change of heart. I've been building this car up since the end of '02. I do not have the time, space or patients that this car has needed over the years. I don't want to see my car float from hand to hand like Hector's SC'd zetec.

I feel like an ER Doctor:

Wait he's not done yet, give him 3 shots of epi - stat!

Breathe damn you!! Breathe!!!!!

OK Doc ( )...
These are pics that I have on file, but nothing has changed in the setup besides the PCV is routed into the intake manifold, and the nipple it once used was capped.



Also, look what the fedex guy just dropped off

Yes, those are tears. Sorry if the pic was somewhat blurry, but I was sobbing.

Man, I really wish I had something intelligent to add. I've been following this thread for a while hoping you get if figured out. The tears pics made me so sad for you.

LMAO, you guys are more bummed out about this than I am

Edit:
Look, I've poured my heart and soul into this car for a few years. I love this car on a creepy level, but one has to know when to move on. I've tried everything I could, but to have a custom built engine take a s$%^ on you after 1000 miles can be a deal breaker on a project like this. I know I could drop another 3L in there with my sweet heads, but that's more work than I have time for. In the end, it won't make my car more valuable as it'll be another $1K when all said and done.

So in a crazy ex fashion, if I can't have Turbo Swazo..... NO ONE CAN

Fatal attraction anyone?
