There's your problem.

Post by bumblebuggy on Thu May 17, 2012 1:22 pm

So I pulled the engine out of the Jolly Rancher today to see why it's making a strange "tinny" noise under load and this is what I found in the trany bell housing...





It appears the flywheel is rubbing. and I'm not sure why. End play seems good. All the bolts holding the engine in were tight. Put a socket on the gland nut and it seems alright (no where near the ammount of torque needed but not loose). Any ideas?

If it is nowhere near the correct torque, Im not sure how it is staying on. They usually come off and cause more damage. How much torque are we talking? I bet if you tightened it down completely, it wouldnt rub anymore. On a side note, how long have you been running that throw out bearing? Ive heard bad things about those. Thats the new sachs design isnt it?

Cept I don't know why it's doing this. Bearing? Streched gland nut!?!? Dowel pins?

Aftr a little more samba research, it appears this engine is likely hosed. If the flywheel has ovaled some holes(my assumption), it seems likely the crank, bearings or both may have been damaged.

Well that sucks! Is it a 4 or 8 pin setup? If it's a 4 pin set-up, maybe the bearings are ok, and you can just get new holes redrilled???

Sounds like its torque tool time. Remove the glane nut and do some inspecting. Hope it's not toast.

Doesn't look like it was leaking oil. I think if it were a bad bearing it would loose some fluid b/c the crank is moving around and the seal would have a gap when this is happening.

Still...trying to salvage it to make a 4000 mile trip seems a little sketchy to me. I did a compression check and all the cylinders are around 100psi except #2 which is @ 87. So I'm leaning towards building another 1600 as I have most of the parts to throw one together. I'd hate to throw a band aid on this one to have it grenade somewhere in west Texas. Sucks this happened a couple weeks before the trip but better here than on the side of the interstate.

Have you pulled the flywheel off. If so sends picture we might be able to drill with larger pins

I will be pulling it tonight. I have a couple more flywheels in garage but now my concern is, if it is/was coming loose, it's put a side load on the bearings and crank which has likely stressed the entire engine. Setting out on a 4000 mile trip with a potential time bomb in the rear doesn't seem all that appealing. But I'm not an engine expert so I really don't know the extent of the potential damage. As of right now, my plan is to build/buy another 1600 longblock. I have a case/crank/rods/heads I just need some 40over bearings, P&C, Sand seal, and maybe a new cam and lifters. Not sure I trust myself though. I've taken several engines apart. Just never put one back together.

I bought a rebuilt 1600 because of time constraints. I will be pulling the other engine apart for rebuild after I return from Cali.
