Various Leaks and opinions needed
« on: April 06, 2022, 19:01:42 »
Dear Members
I had my engine rebuilt in 2015 by Metric Motors and learned the following:

I am leaking from :
1-Front Crankshaft seal
2-Rear main engine seal
3-head gasket
Should these areas be leaking after a rebuild from 2015? I only have less than 5000.00 miles on the rebuilt engine
Any suggestions?
What am I looking at in terms of repairs?

Hi Steven

  I dont think any of those should be leaking so soon. If you re-call I did an engine rebuilt around the same time. For the head gasket did you do a re-torque? after running it for about 500 miles?

I am not a mechanic, so treat it lightly:
1. Front seal - can be replaced without moving the engine out; i would, however, take a good look if it is really this place as there are quite  a few spots in the front that can leak
2. Head gasket - I would, again, double check if it is really this part and not something else; if it is, I would try to re-torque, as suggested; head gasket replacement can also be done without moving the engine
3. The rear seal - this is the tough one. i would make sure it is engine, not gearbox leaking; if it is the engine and the leak is big enough that you cannot live with it or hope it will stop leaking, the repair is major if I recall correctly and may require removing the engine from the car.
