First thing that comes to my mind is the timing chain. Could have jumped time.

My mechanic checked the timing......still in time, just 5-10 lbbs. of compression 4 cylinders.

Has he spayed oil in cylinders and retested for compression? It called a wet compression test.

will do, thanks.

If its does not increase compression with a wet test I suspect a head gasket could have failed. I see that car has had some failures of compession loss due to head gasket fail in a site that we track commom failures of specfic car makes.
