I'm trying to help a mate out who has quite a nice auto sleeper conversion T25, the van is a 89-90 2.1 injection with auto box.
Problem 1.
A friendly type garage took it in to fix an exhaust blow where the offside front pipe bolts to the cylinder head, they broke both the heads of the bolts and advised him it would cost a ridiculous figure to fix and come and pick it up.
There is about 1/2" of bolt sticking out on both so you can get mole grips on the remaining bit, but they don't want to move.
Any ideas on removing the remainder of the bolts would be greatly appreciated

The exhaust is still on the vehicle and appears ok ish, it was just blowing from the joint in question.
Problem 2.
On closer inspection and removing the cover beneath that particular side, it's obvious that the oil is coming out round the push rod tube things as well as other places.
I checked the oil and water and there was no oil on the dipstick and the expansion tank was empty, I didn't find any creamy type deposits but was told the water was a little oily on last check and my mate assumed/blamed his wife for using an "empty" oil can to top the water up?
Suggestions here please.
They love the bus and want to keep on using it, I can see that the exhaust will want replacing sometime [sooner than later] but fear all the bolts into the cylinder heads will do the same thing.
Last year they spent a fortune having the autobox replaced, it is a nice tidy camper used predominately by the wife and children so they do want reliability.
They are paying me to try and sort this out, I want to give them the best advice and not take their money if their just wasting it.
Cheers
Brian.
P.S. I'm not a garage just a mate that's not got a lot of work on so offered to have a look for them.
