No they don't. TDI has 12mm bolts, 20v has 11. Use studs for BMW 3.5L BTDT

Roger

I think Marco (Pisobiker) used Audi A2 Diesel Studs!

Do you need to drill the holes in the head larger to fit the 12mm head studs?

these are the BMW studs you need i think.

[olsonjus]

Yeah, those are the ones I ment to post. I mixed up the links. So does the head need to be drilled to clear the larger head studs?

Head was then skimmed 0.02mm to clean and flatten mounting surface up.

Seats have been reworked, valves received a three angle job, guides remained standard.

Studs holes have been enlarged to 12.5mm to accomodate “TDi specs” head studs.
For this purpose I’ve used M12 x1.75 studs of the A2 1.4 TDi (AMF) engine, cut back 20mm.

Damn, I need to work on reading comprehension

Hi, did someone knows if pisobiker used the Diesel or the RS2 Crankshaft bearings? I have heard that the Diesel ones are not the same as the RS2 ones and the first are not so good at higher revs! What do you think?

[Billman]

Where are the Differences at the Oil pans of the different 5 Cyl, with Climate and without? In the 1. Page of this thread we can see the Diesel oil Return line hole btu Marco is using the one on the oil pan? anyone having ither pictures? Can the Diesel oil retun on the Block be used or it cant be done? where is the Air-Con mounted on the Block? there where these holes are?

Thanks

[caterpillar]

you may use different oilpans( i will use the org vw quatum one of steel ) the oil return in block, you mau use it( std releaf in all block) diesel use thoose for oilsticks: rebuild those... the air con; compr are on the block under the servopump i think.

[Billman]

In the Rs2 the Air-Con compressor is on the side of the turbocharger. The question is can i Use the oil return on the Block and let the Air - Con in place?

[caterpillar]

yes. you can use the org oilreturn in block.so said the famili album...
