First, hop on one foot, and then shout "Crap!", and then wait for someone else to chime in on a 4 cyl valve ajustment, Since i have no idea myself how to do valves on a 4 cylinder. :D Sorry i couldnt help much on that point, But it sounds to me like your valves are staying open.

Scroobs,

I looked at the valves and adjusters and it looks like one of the valves is stuck open and there is a gap between the top of the valve and the valve adjuster. I have attached some pictures.

Hydralic valve adjusters. No adjustment. Spray a little pb blaster on the valve stem and tap on the one that looks stuck open and see if it will spring back up. Who rebuilt the head?

Blue Rhino,

No outside rebuild of the head. I cleaned it up and replaced all the valves, lash adjusters and valve stems.

Bent valves binding up in the valve guide? Just a guess.

Starscream5000,

appreciate the insight. Appears that two of my Intake Valves are not the correct length :holycrap . I am working on getting them replaced and hoping that will resolve my no-start/low compression issue. :ermm:

Hi forum members. I need your assistance. My Blue Beast starts now but I have other issues with it. Although it starts, it won't restart if you shut it off after it has been running and is warm. I don't find any oil or coolant leaks; however, the I am not sure the coolant is circulating because the upper radiator hose remains cool to the touch even after it has been running for 15-20 minutes. The radiator fan will come on but the coolant doesn't appear to be flowing. Also, if I try to give it gas while it is idling the engine will shut off.

I need the benefit or your knowledge so that I can get my Beast running properly for my commute to my new job. I can provide pictures and/or audio of it running, if needed. Thanks in advance for all your help.

The first issue sounds like a bad thermostat. Take it out and put it in a pan of boiling water and see if it opens or not.
The second part could be a few different things. Map sensor unplugged or no vacuum hose going to it, TPS out of adjustment, or some other sensor unplugged...

Starscream5000, I don't know how to read the schematics in the FSM. Where is the TPS located on my G13?

It should be under the TBI hat, left hand side of the motor as you're looking down at it. Its on the throttlebody assembly.
