1997 GTX Milky Oil

[etemplet]

Picked up a 97 GTX on Tuesday. Pulled the plugs and compression looks pretty good. I got a good bit of milky residue spraying from the rear cylinder upon rotation. Front cylinder looks fine. I just purchased the machine and wondering which leak paths should be checked.

Sorry for posting to the wrong forum... this is certainly not a performance topic. LOL

Sounds like you have water in the rear cylinder. If that’s the case the engine is shot and needs a full rebuild.

Try getting all the water out and run it if it is steaming then that means the you probably have a head gasket leak.

If the water has been sitting this long the engine is still shot.

You sir are correct. Check my other thread.

What u gonna do with it

 

[etemplet]

Buying parts and rebuilding. Everything is bad. Crank may be OK for a core.

What’s the cost for that?

 

[Cliff787]

A full crank rebuild at a reputable shop for a 787cc is about $425...

A full engine rebuild at a reputable shop is about $1,500.00 with a reusable core.

Just an update here as I started another thread in the 2 stroke forum. the only thing that was usable in the end was the Mag section. That was in great shape. I have not been able to reuse a single engine part, include the engine cases. I bought all the parts I used off Ebay. LOL I can't call it a rebuild because I threw everything in the trash can. It was an experience for sure. I am now waiting on a starter. Of course that was/is bad also. Why do I love this kinda work so much?? I think it is being able to resurrect old equipment an give it new life. The ability for it to fulfill its purpose once again.
