LOST JEEPS :: View topic

If anyone was reading my other thread, you may recall I was trying to remove the turbo & manifold and complaining about the difficulty. I could only see/feel 3 turbo mounting bolts, even with a mirror. So that's all I could spray with penetrating oil. And that's all I took off.

The FSM and all the pictures I could find showed a 4 bolt mount. Mine is only 3, as is the manifold. It is a Garrett M53. Serial number is 00035. Could I have a very early model? Maybe Jeep/VM switched early in the production run for strength?

Anyone familiar with this?

I'm guessing my IDParts headgasket kit's turbo gasket won't fit...

The export models with the old 2.5 and early 2.8’s had 4 bolt flanges, but had a fixed geometry IHI turbo. Ours are variable geometry Garrett units. The later engines had a Garrett GT1756 that i *think* had a 3 bolt flange. Id need the model number to clarify.

Also M53 means nothing, its casted on about every compressor housing ive seen.

Don't know if this works or not. Sent pictures to Mountainman.

It all seems pretty tight to me. Only 101,xxx miles on it.

So anyone know why or when they changed over?

What is the manufactured date of your CRD?

Since I have only ever heard of two of these (and never seen it in person)... I'm wondering if in fact this is the same truck that I heard about last time. How long have you had it?
I wonder if it was somehow a development platform model, which is why I'm curious about the manufactured date that will be on the door sticker.

I likely have the turbo to manifold gasket for you. Free, as I was sent it from Europe by mistake. Yeah, pics x2 Edit, but the euro version doesn't have egr right?

Man I do well to type on a forum let alone post pictures. My phone is a flip phone... But, I can take pictures on my ipad and email them if somebody wanted to PM me their email. I have mastered that.

Export CRDs do have an EGR....early 2002 KJs have a non-cooled EGR but after that they were water cooled. I may be wrong though....maybe some European countries received different setups. My 2002 Export 2.5L CRD has a fixed vane turbo....variable vane turbo came out in 2003 I think when that went to a 2.8L motor and automatic transmission....do not know how many bolts hold my fixed vane turbo in place and do not want to tempt fate by searching around that area!

Post subject:	Re: Early Turbo?
Wow, you really do have a different, likely never seen before on our CRDs turbo and exhaust manifold! With any luck the internal dimensions are the same, and dieselguy can upgrade and rebuild your turbo, because you will likely have trouble getting one of those stateside. Or, you just buy a manifold for $100 when the time comes. But, you might need a different feed and return oil line also. Oh, and maybe a turbo to block mount. I know chrysle was pinching pennies by using up old stock, but this is a new one. I guess this was VM sending them something different, hmm -please send me a picture of the complete manifold that shows the egr port. -dont lose that metal gasket. Is it basically a square with 4 holes that don't reach out/cover the entire manifold flange? If so, I have a lifetime supply of them you can have (6+).

Post subject:	Re: Early Turbo?
On a side note, for the turbo experts: Is the M53 or whatever it is any better or worse than what we have stock? Coincidentally I have been in the process of getting a price for the turbo they used in Europe (M53?), just in case they were much less costly. I was going the route of the make and model, not the part number... Krb, Are there any contact/ scraping marks on the housing from the wheel? And is there any play in the shaft? Ithink 1/32" is about the max. I've ended up with 3-4 CRDs that failed and ran away from the turbo failing, I'm rebuilding one right now. Smoked every bearing in the motor and more...

It's tight, and relatively clean. I'll look closer today and let you know.

Ok, it has the following numbers on the plaque. 35242106F 752150-(3?) The 3 is tough to read. Then there's a SN# It looks to operate the same as ours with a similar vacuum actuator

Yours would be the second 3-bolt turbo I've seen or heard about. You can use the 4-bolt gasket, but you will have to drill out the hole that is obviously missing. You can also just reuse the old gasket, it isn't a huge deal to do that.

I'll check tonight. I got it from my dad who got if from a fellow in Tennessee maybe 10 years ago? He thought he remembered he had been a dealer or something.
