Changing sump with engine in car t5 l31. My experience

Vortec L31 with a pro flo xt intake and a t5 transmission. Jack had slipped from k member and sent the steering bar into the sump. Dent was maybe a half inch in but across the sump. Despite it being relatively shallow, engine wouldn’t turn over by a breaker bar

in short sump slid out fine by raising the engine at front with a cherry picker after removing engine mounts and all the other stuff as mentioned in prior write-ups (y-pipe, starter, distributor, transmission inspection cover etc.). Didn’t touch the transmission and it was left connected to the engine. I used a tow rope around the front header pipes hooked on the cherry picker and didn’t have to remove the bonnet

One additional annoyance was the engine oil cooler which I effectively had to remove from the oil filter connection and hang it down. It got in the way often!

prep to raise the engine was about 2 hrs. Raising engine and changing the sump an hour. And another hour- 2hrs to re-install all the bits I took off.

oh yeah I had a fel-pro one piece gasket which looked fine so I didn’t replace it. This is a crate engine with less than 100miles on it. We’ll see if that bites me when I fill it up with oil

Whilst prepping for this and reading some posts on here (invaluable) I saw a few comments that you couldn’t remove a sump with the engine in on a t5 car; in my experience you can

And whilst not a pleasant job, I wouldn’t say it was particularly difficult. Just took time and a little fiddly. I suspect the real frustration comes from rusted bolts etc. which luckily I didn’t have to deal with (only recently have got the car back together)

Good information. It's further evidence that there is more than one way to skin a cat.
