85 5 MGE leaks oil

contryman · 01-07-2010, 10:08 PM

I had our 85 5 MGE engine rebuilt but it still leaks oil. I think it is leaking between the cam shaft housing and the head on the exhaust side of the motor.

Can I remove the cam shaft housing and replace the gasket with out removing the head? Do I need to readjust the valve lifters? What other precautions do I need to be aware of?

I know how to keep the timing correct as I have replaced the head before and put all the bolts back in their original places.

The TSRM for the '86 MKII is available for viewing online. I hope it covers what you need. I know the diagnosis system is different in earlier years though.

Here is the link to the section for working on the head: http://www.cygnusx1.net/Supra/Librar...ection=EM&P=18

I hope this helps.

As for timing, resetting the mechanical timing is simple enough and you'll find it covered in that manual in the Engine Mechanical section and Ignition System. I do not know the procedure for setting the ignition timing, although you should set it after you reinstall the timing belt.

Yes, it can be replaced without removing the head. Exhaust side should be a bit easier. I haven't actually done it, but here is a good link with instructions and suggestions on gaskets...
