Can anyone please tell me how this job can get done with out breaking the
bolts and making the job more expensive etc.
No ! There are lots of tricks but NO guarantees. Welding a nut to the end
but the bolts at the rear would be almost impossible to do that due to space
restrictions and that's the same reason that if those ones break off, the
next best thing is to drop the engine. No way you can go there with a drill to
drill out the broken studs & bolts. Penetrating liquid can be tried but must
be continuously applied and the area heated over a few days to have any
success and MOST times the bolts & studs STILL break off so your just wasting
time. Something that most shops won't want to do unless you willing to pay for
this. DO NOT REMOVE THE HEADS. Your just asking for more problems doing
that. If the nuts and bolts break off the best way is drop the engine. Then
remove the remaining bolts & studs the best way you can. Then drill out the
broken bolts & studs, fit helicoil thread repair inserts to all eight locations
then use stainless steel bolts of the proper length at ALL locations. Don't
forget abut flat washers, lock washers and the mounting tabs of the push rod
tube covers when calculating the length of the bolts. If the bolts are too
long you WILL crack the heads and if they are too short you will not get a
good seal on the flange. Clean up the exhaust port gasket surface before
putting the engine back. Good clean surface here is IMPORTANT to having the
gaskets seal well. ALSO, use Loctite Ultra Copper High Temp Silicon Sealant on
both sides of the gaskets.
To make all this expensive work worthwhile and to not have to visit this
scene again sometime in the future think about fitting a stainless steel exhaust
system. See my _STEBRO/Vanagon Stainless Steel Exhaust System_
(http://members.aol.com/Fkc43/stebro.htm) webpage for complete details on what I have to
offer.
