2006 Toyota Matrix Q&A

2006 Toyota Matrix Question: lost all compression on all 4 cylinders....car was running fine..just died

running along on highway, car was running fine, started slowing down & just died. Heard slight ticking sound. -
Answer 1
First thing that comes to my mind is the timing chain. Could have jumped time. -
Comment 1
My mechanic checked the timing......still in time, just 5-10 lbbs. of compression 4 cylinders. -
Comment 2
Has he spayed oil in cylinders and retested for compression? It called a wet compression test. -
Comment 3
will do, thanks. -
Comment 4
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. -
Answer 2
Was it low on oil?...... -
Comment 1
no....and it has only 55,000 miles on it!! -
Comment 2
I would be interested to find out what happened when you find out whats wrong with your car also...Good Luck -
Comment 3
Thanks.....he's pulling the head off as we write. -
