1990 Cressida no compression

I have a 1990 Cressida with the in-line 6 twin cam engine that has no compression in the first two cylinders. The other four cylinders have 180 psi. Does this sound like a blown head gasket or a valve problem? I tried adding oil to these two cylinders to get some compression, but it did not make any difference. Any ideas?

Thanks.

Either way you are going to have to pull the head. What were the symptoms that led you check the compression?

I would check for broken valve springs before I pulled the head.

Re: 1990 Cressida no compression

I got the head off last night and it is definitely a broken head gasket between cylinders 1 & 2. It looks like it has been this way for a long time. I am going to take the head into a shop and get it checked. My concern now is for the injectors. The injectors for cylinders 1 & 2 have carbon build up on them and the ports are clogged with carbon. I don't know if they can be cleaned by hand, I figure it is safer to just replace them. The wiring for the injectors seems to be old and brittle. I found a break in the insulation of the wires for the first injector. The copper wiring has some green corrosion in it. I may need to patch some of the wiring. This will give me some practice with my new sodering iron.

Thanks for the input.

While you have the head off use a flashlight and look for a crack between the two cylinders. Then use a straight edge and check the block. While it is generally the head I have found small cracks between the cylinders. They usually fix these with two piston liners.
