Dont you have to disconnect a lot of hoses? And also drain the radiator? There's also lots of hoses going to the firewall that will have to be disconnected or cut.
Thats the plumbing and wireing I spoke of.
Last week is the first time that I didn't pull the rad and just pulled the fans.
You need to do a skill, committment, and time assessment like GG basically said.
I work at my own pace (slow, emails, USMB, stock trading) and figure roughly 4 hours out, 4 hours in, 4 hours to work on the engine (HG's, seals, idlers, TB, etc.). I do most everything myself. Sometimes I'll have my dad come help with engine alignemnt, seperation, and have him start the car while I'm outside the car. But really I do all the work.
I do have a cherry picker, engine stand, and a car lift. The lift is really because I have a bad knee but it does give some advantage on this job.
Some folks claim to be real quick. I prefer to be thorough.
Now it's been 2 weeks ago that a Suby tech helped me fix a bad crankshaft end. We were both used to working alone. We had the engine out in about an hour. Fixed crank(weld, grind, Dremel keyway, grabbed parts off 3 parts engines(harmonic balancer, crank bolt, oil pump, TB cover) , TB, idlers, seals, WP, Oil pump O ring, etc. A little Pizza, etc. Trip to parts store (exhaust gaskets and I forget what else)
Reinstalled and running within 5 hours. He came at 10am and left before 3 but I didn't really keep track of how long it was taking us. But it was intense - definately not my usual speed.
There are some excellent Endwrench articles on the whole process.
And a link that I can't find from comcast.net skipnospam or something.
