OK, I made the STUD out of 2 of the OEM bolts I took out last week to learn why I could only trun my engine +/- 170 degrees after a belt change out of the car.... Yes, I timed it 6 times on 3 separate days thinking I missed some detail. More on that later...
to the head torq.... The gasket comes with these instructions:
1) 29 lbft
2) 43 lbft
3) -90 * +43 lbft
4) 90*
5) 90*
6) (.)
8) (..)
8) (...)
9) 90*
And Bentley says:
1) 30 ft lb
2) 44 ft lb
3) use breaker and turn each 180 degrees in one motion.
4) warm engine to operation temp
5) 66 ft lb
6) turn each with breaker 1/4 turn
7) drive 1000 miles
8) hot or cold loosen each 30 degrees
9) 66 ft lb
10) with breaker bar turn 1/4 turn hot or cold.
What does the gasket maker mean ?
Should I use Bentley instead ?
-
get studs instead 8) :lol:

uhhhh a buhhhh uhhhh... oooo errr
I used 36, 44, 90 degrees,90degrees again, up to temp/few days of driving, 90* (all of these were done in one motion, except for 36 ft/lbs obviously)
and that sounded very familiar to the instructions on what my HG came with and what my diesel mech. friend told me at the time (about a year ago) but some may be different.
29, 43, -90 degrees, back 90 degrees,90 and then 90 after its hot seems like you're missing 90 in there but then .... for what the bentley says: 180 degrees all at once and the heat up and go to 66 ft/lbs.... wont you be well past 66 after your 180 degree turn? good grief and the loosening and then 1/4 turn again at the end just seems so elaborate and borderline ludacris

Sorry, I thought I was the only guy doing a VW 1.6L diesel into a Dodge Caravan...
It it a 1.6L turbo block 1982.5 block with a 1.6L 1984 head with an intercooled turbo post morten. It has 12 mm bolts.
I have the bolts now at 44 ft lb - so getting studs now in not in the cards ;-)
What do do ?
-
if possible i'd use the info from VW who designed/manufactured the engine. afaik that's the bentley info.
-
On vortex didn't you post that it was a 82 head?
-
Yeah, I was mistaken on vortex about the head's year - 1979 would be an 11mm... no one had a clue there either, so I guess I flip a coin.
afaik ?? What's that ?

AFAIK = As Far As I Know
1980 and some 1981 heads are also 11mm. A 1979 or 1980 head will be a 1.5 head, and have smaller prechambers in the head than a 1.6 head will.
-
what size bolts are you using? Are they 12mm?
-
Yes, they are 12mm bolts. The ones I took out of the engine last week have threads all the way up to the socket head. These new ones have a shoulder on about 2cm of the bolt at the socket. This results in a washer that is captive.
-
neither of the procedures you listed sounds right to me,
The Reinz and Elring gaskets I use always have this procedure listed - it's the same as the Bentley -at least for mk2's IIRC, which is the most up to date info.
1) 29 lb-ft
2) 43 lb-ft
3) 90 degrees
4) 90 degrees
5) bring engine coolant to operating temp (80c)
6) 90 degrees
7) after 600 miles (1000k) - 90 degrees
FYI a quick search for "torque sequence" yielded this post
http://www.vwdiesel.net/phpBB/viewtopic.php?t=13016&highlight=torque+sequence
which addresses your issue :)
Search is your freind

Thanks Myke.
I tried to search for Head bolt, head bolt torq, bolt torq - and didn't get that thread. I never thought about the sequence as I already knew that and there was no dispute. :-)
I joined the forum after that one was posted, so I really appreciate your help finding it. :-D

Sorry, should have also mentioned, I always do "Search for all terms"
