91 lude B21A1 Engine Advice Needed.

Hi, I just purchased a 91 Lude SR with a 2.1 B21A1 engine. Apparenly the top end has been rebuilt as the timing belt went and took some rods with it.

The previous owner told me he drove it for 4,000 kms and noticed a knocking one morning. he dropped the oil pand and said the 2nd connecting rod bearing seemed to have some play. He replaced the bearing, but just tightened the bolts up as he didn't have a torque wrench. He also said some other piece that runs the length of the crank was tighted up without torquing it. The oil pan was then put on.

He started the engine, and he said it sounded "tight" (I'm not exactly sure what that means???), and it was leaking oil. He got pissed off and parked it. I figured I would have to pull the engine, but he said you can get at the bottom end easily without pulling it out.

I'm not a mechanic, but have a fairly good understanding of engines, although I've never rebuilt one.

I plan to use a dolly to take the car to a shop where I can work on it. This place has a hoist.

Question: I plan not to start the car as I'm afraid if he tighted things up to tight there's a chance it may damage the crank (tell me if I'm wrong in this assumption). I plan to remove the oil pan and have a look.

Can somemone advise, based on the above, what I should be looking for?

Sorry for the sketchy details, but that is all I have to go on.

Thx....................kd

You will need a service manual to know what the torque specs are, so start with that first and do a lot of reading before you start this.

Here is a link for a downloadable manual: http://www.teaminterlude.com/Documen...en/1990-91.pdf

...well, the previous owner is a dumbass. How can u not tighten main bearings to factory torque specs? yes, this could potentially damage the crankshaft, depending on which way the bearing now sits. By removing the oil pan, if you dont know what you're looking for, then it'll be a little bit confusing. Download the manual which is located in my sig and i suggest you ask a mechanic to look at it firstly...if you can, take a pic and show us.

Good luck!
