Re: 1987 VW Quantum Syncro - convert to 1.6 turbo diesel?

Libbybapa, I want to stay away from any of the electronics of the TDI's. I have no experience with creating an MTDI or working on any of the TDI's so it's likely out of the question for me. I only have 1.6 TD and Cummins 12 valve experience and feel confident working on those from complete rebuild t...

Re: 1987 VW Quantum Syncro - convert to 1.6 turbo diesel?

It looks like the 2.0L Turbodiesel Audi will fit right in, engine code DE. It also appears there's a later European version, code NC that has 100hp. There was one (the DE) on eBay for $750 that someone just bought. Was that you bbob203?? :) It also appears they come out of the 1981-1987 Audi 100's a...

Re: 1987 VW Quantum Syncro - convert to 1.6 turbo diesel?

Excellent link, thank you. I was aware of the existence of the 5 cyl TD but have never seen one. Maybe if I start looking I can find one.
I am scheduled to look at the car in two days and will make a decision then.

Thanks for the data! I'll know if I'm still interested after I look at the car tomorrow.

1987 VW Quantum Syncro - Convert to 2.0 turbo diesel

I'm going to look at a Craigslist listing tomorrow for an '87 Quantum Syncro that has a 5 cylinder non-turbo gas engine. Would it be possible to put in a 1.6 turbo diesel and have enough power to drive it at 75mph on the freeway. I have the engine and am VERY interested in having an all wheel drive ...

Differences between turbo & non-turbo head?

I have access to good a 1.6 non-turbo mechanical head that I want to use to replace my tired old worn out 1.6 mechanical turbo head. What are the differences? Hardened valves? Different cam? The non turbo head was reconditioned by a friend of mine and is in great shape. My old turbo head is currentl...

Re: Head bolts final torquing. The final 1/4 turn.

Quote from Mark (The Miser) UK on the TDI-IDI site: This is what I have personally experienced. This is for M12 stretch bolts I use a Snap-On dial gauge torque wrench. IIRC it's 2% or better. Initial angular torquing peaks at approximately 115 to 125lbft. The final torquing only reaches 95 to 105lbf...

Re: Head bolts final torquing. The final 1/4 turn.

When these engines were new, right off the assembly line, did the owner bring the vehicle in to the dealer to have them re-torqued?

I'm having trouble making a decision to do the final 1/4 turn since I've driven the car over 2,000 miles since replacing the head gasket.

Re: Head bolts final torquing. The final 1/4 turn.

A quote from "demon" with "quantum-man's" replies, very interesting as it relates to my original question about torqueing the final 1/4 turn: demon: So i pulled the head offf today. Head looks great, no cracks, all cylinders look to be burning evenly and the same. The cylinders l...

Re: Wheel bolts & hubs/drums. Breaking & stripping. Soluti

The problem with the front hubs is likely PO over-torquing or cross threading or just old hubs or lack of care in reinstalling the wheel. When I had the tire shop re-mount my tires (they only snapped 2 before I started mounting my own wheels) they snapped a wheel bolt and said, "They get old an...

Re: Head bolts final torquing. The final 1/4 turn.

Adding a few more quotes from related posts for my own reference: Quantum TD: Jack used to claim that you didn't need to do the 1000 mile retorque unless it was seeping. Something about the new head gaskets or something. I just get leery on that last round. It seems like everytime I try to do it, I ...

Re: Head bolts final torquing. The final 1/4 turn.

I found the post from Quantum-man.... I need an explanation on "when the plastic position is reached". I can't find Fats' or Quanutm's original post. Quote: 1000 miles is too long. Bentley transcribed 1000km to 1000miles when plagerising :shock: I believe in about 500 miles revisiting the ...

Head bolts final torquing. The final 1/4 turn.

It's been over 2000 miles since I replaced a head gasket and I still haven't tightened the bolts the final 1/4 turn. Is it wise to do it now? On another post which I can' find now someone had a suggestion for the final tightening: loosen each bolt individually and then re-torque per the book. Or may...
