Can Anybody see these pictures? If not i need help uploading pictures on here. Is there anywhere or way to just click and drag the photos? I feel like i'm writing code in 7th grade geek class!

Now if any of Fred Flintstone's pictures from his 85 cali went through here is what i sent:
1: Picture of pipe that use to comes down from egr to exaust. t is leaking out through where it hooks into exaust, would this cause lack of boost?
2: The gap inbetween the turbo and manifold. I think it's ok but not sure if there is supppose to be a gap here or an o ring or what?
3: Where i disconnected and plugged everything. Took off vac lines and plugged with bb's. Would like to take off egr all together and plug exaust pipe.
4: Manual boost sdjuster that i believe i wasted 20 bucks on, it made no difference whatsoever.
What tells the turbo to turn faster?
Anf thanks i will pick up a hex socket set!

Sorry, no pics.

Sounds like you need a couple of block off plates.

What is a manual boost adjuster? What car is this?

The more rpm you have, the faster the turbo will spin.

Not to Hijack your thread or anything, but my question is on topic... I just discovered a previous owner had disabled the switchover valve, so my vacuum line goes direct from intake to alda. The valve is still there, so is there a way to test it to see if it functions correctly?

To don b, since I'm hijacking, I'll try to help too. I believe there is someone on here who makes a kit with blockoff plates and instructions. Brian Carlton sound right? Someone correct me if I'm wrong.

My block off plate......All looks factory and untampered. Just copied the gasket in metal with out the big hole!

I used a piece of galvanized steel I had around the garage. Drilled some bolt holes, Snipped it out, and ground it down on the bench grinder to match the shape. A little high temp RTV and done.

About 20 minutes tops and it was FREE!

If you have some small holes in the tube between the EGR and manifold that can be filled in with a little JB weld. You should still have some boost though.....

i have lots of rpm and 3 pounds of boost @ 4rpm, that's what i'm trying to fix. something "tells" the turbo to go faster. It's either pressure from exaust, manifold, something???? there is no electric or anything making the turbo spin faster is there? what makes it go?

manual boost gauge is a little device that goes inbetween the hose that goes to the wastegate ( you split it in two) it adjusts the wastegate somehow so if the spring is worn out in the wastegate, you can adjust the pressure using this little device. i put it in so i didn't have to take apart the wastegate. i didn't think i could get it back together correctly. i'm losing air pressure somewhere so my turbo won't spool up i gues, but i can't figure out where

This has become more of a turbo boost questions and might be good to use the search function or just repost. I'm not great with the turbo operation, but seems like the either the wastgate lever is not operating propertly or not opening all the way as it should.

Exhaust flow should propel the turbo (especially at 4000 rpm) and create plenty of boost. Have you checked the play on the turbine from the front for wear?

I'm thinking that if you had a pre turbo exhaust leak big enough that you could only spool up to 3 lbs, you'd be able to hear it easily. Pop the hood with the motor running and see if you notice a leak. If the egr is broken in half, and not plugged it should be blowing exhaust big time!

Here are the pics of my 85 california i couldn't get on before.
Refer to post #22 for what they are thanks everybody for the help!

I have major exaust coming out of the pipe that use to be hooked up to the egr! if i plug that will that make the turbo turn faster and give me more boost? Plus if i took off the resignator and replaced the muffler with a glasspack would that have less back pressure and also affect the turvo? thanks

I would think the boost is going out of the broken egr pipe. Not sure it the turbo is missing some support.

Holy crap, you've got exhaust blowing all over your engine compartment. Yes, plug the hole. I'd buy or build the plates to do it nice myself, but whatever you can do will help.

i have the erg hose plugged with a bb and the bottom crimped over so i think it is plugged off now, do you think i should take off the erg anyway if i feel there is no air leaking out? would a little air leak out of the erg cause very much of a loss of boost? how about the back pressure from the exaust? does back pressure from the exaust tell the turbo to turn faster?

The exhaust pushes the turbo. A little reading on the basic concept might help you:
http://auto.howstuffworks.com/turbo.htm

What the egr does is divert some of the exhaust gas, before the turbo, straight into the intake - the theory is that it cools the combustion and makes better emissions - the reality is that it just makes a huge mess. If it is broken open, you've potentially got an exhuast leak, an intake leak, and a vacuum leak.

So you'll want to make sure of 3 things
1 exhaust isn't flowing out - if that crimped end isn't leaking, you should be OK for now - I doubt it'll last forever.
2 the vacuum line is plugged - BB should be fine.
3 the intake side isn't leaking. The BB should keep the valve closed in theory, but I'd put a solid plate or a gasket without a hole, or something to make sure your boost pressure isn't escaping out there. You could take the intake side of the egr off, and make a blank gasket (no hole) out of tin from a beer can. A little RTV to seal it, and problem solved.

Also, the leaks might seem minor at idle, but going down the road under load, all the pressures go up.

Hope this helps!
