I know the car needs the engine/seals redone. The question for me is, do I just buy a whole new motor from a reputable builder (lucky7 has a motor for sale, and some other shops have some motors for sale) or do I just bring it to a local mechanic and have them replace the seals.

The motor right now has brand new rotor housings (2,000 miles on them) with 3MM seals and is streetported.

I've been quoted by Karack (Ben) to pull the engine, replace the seals and put it back in, however, he wouldn't be able to get to the car until a month and a half. My worry is that although the engine has new rotor housings, how do we know that the rotor housings or even the rotors may be damaged and I will need to buy new housings/rotors and the cost is a lot more than buying a new engine built by someone and then just paying someone to pull the motor and place the new one in. I could then sell the old motor to make back some of my money.

What would be the best thing to do?

 

the best thing to do is take apart the motor..

and buy some of the small tools you need to check the specs on the motor...

but if the rotor housings and other parts are new.,. i would just get your current block rebuilt. if it has low milage..


and which seals need to be replaced??? the apex seals? springs?,water seals????

depending on which seals you need. the motor should be fine..

 

We don't know what seal needs to be replaced as I just got a compression test, but my mechanic said that it could either be a side seal or apex spring since we are thinking he didn't break the engine in properly and just romped on it since getting it.

 

So did you get burned or you still think you got a good deal on it?

 

well if its just low compression it could be that the apex seal springs went flat(due to improper break in).

lets hope its just flat springs because all would would need is the seal kit,( just would need apex springs, maybe side seals, corner seal springs, water seals, oil seals, etc)

but some times low compression can be cause by a chipped apex seal( lets hope its not)..

well in either case let us know how it goes..

 

Seeing that I knew the car needed a rebuild before I bought the car, I still got a deal on the car. Now if he would of sold me the car at the price he was asking and I didn't know that it needed a rebuild I would have been pissed. He took of $4,000 to help cover for a rebuild. If it's just the seals that need to be replaced, the cost/labor is around a $2,000 job so I'm still up $2,000 for any small things that need to be replaced (even if a rotor or housing needs to be ordered, I'm still up)
