Hi.


So now that im removing my engine to replace it... I Have a few questions...





1. Is there an easy way to get the exhaust bolts off (all 6)

2. should I remove the transmission with the engine if so, is there a way to just remove the engine without taking out the tranny with it.


thanks for the help

it would be easier to take out with the tranny especialy if your taking it out anywys. there is torqx bolts on the belhousing you cna take those out if you want to remove the tranny b4 pulling, id do it with the tranny that way instalations is easier, put it up on jackstands (the front) that will make removal easier, and the exaust bolts just come off easy, shouldn't have any problem with those, maybe some liquid wrench or similar product.

the problem is we cant get to the 3rd bolt on the back of the exhaust pipes any tips?

if you are working at a shop, or maybe even in your garage and know what you are doing, try this.

1. get a torch and heat up each bolt till its pretty much red hot. (do this one at a time)
2. and then as soon as it gets hot enough. pour some cold water on it immediately.
3. grab a nice pair or vice grips (if you've sheared the bolt) and it should come off very easily.

i have done this many times with a cheap 20 dollar torch kit from home depot.

your other alternative is to weld a nut onto the bolt and then use a big breaker bar and impact socket. which are like chrome vanadium or something like that.

good luck

also if absolutely necessarry, drill out the old bolt, tap and thread it and replace with a larger bolt.

Two wheels or Four, I'm happy as long as the throttle is pinned.

you can but mating them in the car is a pain in the ass, i didn't take it out when i did my engine swap but it might be easier to mate them outside of the car... its all on your opinion. its also easier to reach the bellhousing bolts out of the car. but put the front on jack stands to get you more room to play with.
