Thread: CapnBreakAlot's Regal

Got the modded rails, 42.5s, ported blower and phenolic spacer on today... Aaaaand have a big boost leak.. only making 7# on the 3.4.. looks like I'll have to tear it apart again before Friday.

You think you have a leak...because of the boost number?

You should look for vacuum leaks, because if you have a boost leak, your car usually runs bad under vacuum.

the cam should lower your boost, not raise it.

You can hear it under load. Around 3-4# you can hear a screeching sound.

I made 11# on the 3.4 with rockers, I made 9# with the cam before the 1/4" spacer, now I'm only seeing 7, I saw 8 once at the top of 2nd.

Screeching under boost could be a sign of a pcv issue......when you take your oil cap off is there sucking?..maybe the spacer blocked pcv or messed it up..not fimailiar with spacer.

Screeching sound maybe belt slip? Did you have to buy a longer belt with that spacer?

I wondered about that but there's a hole for the pcv there.. I'll have to look at it again.

A hole..there should be two.

What I have looks exactly like this. There are holes for the pcv. No sucking or anything if you remove the oil cap. I think it just didn't seal right.

You could be hearing your seals scream


plus 7lbs of boost does seem low for 3.4 and s1x I think was still in the 11s. 14 with a 3.0

I know I have belt slip but it was going from 8-9# before the spacer, now it jumps from 6.5-7#. I'm pulling it apart and resealing it tonight hopefully. Any tips on using dimes to block the coolant passages? Will they fit right in or do they need ground down on the OD?

I might have had to grind the edges down a bit but they pressed right in Then some use jb weld and sand afterward.

So you are using a spacer under the blower not a IC?

Yep just the spacer, no IC yet.

Just treat me like a dumb blonde... What's the spacer for? Lol

It's a phenolic spacer, phenolic material has no heat transfering properties, so it helps with keeping the heat of the motor rising up and heat soaking the blower.

Soooo being right above the exhaust in the enclosed engine bay doesn't transfer any heat once the spacer is in place...right?

Of course...

I'd bet heat doesn't rise in your engine bay either..

Well, hot air falls so... nope.
