Thread: Help! What have I done!

Hi Hammer head, it sounds like head gasket doesn't it?

I would pull the glow plugs out and crank it over, or the injectors ( disconnect the "run" solenoid on the fuel pump). Plus have a look in the rocker cover for for brown foamy looking emulsion. If the starter can crank it over it's not likely much damage has been done. I think a head gasket would not be too big a job on the the old isuzu. good luck simmo.

Thanks simo,
Suns just poked its head up time for some investigation!
I'm really really hoping it's something simple. Time to get covered in crap again!!

Ah amazing! A little sun light and a lot is revealed! There is a major lack of coolant thru my system! I don't know why yet but I topped it up 2 weeks ago and it has been running fine. No unusual noises or strange sounds on start or shut down. Although now I have opened up the cooling system. Taken the thermostat off I have discovered a lot of corrosion thru my system.
Right now I am preparing my self for the worst.
I'm pretty sure I'm up for a new thermostat a new water pump and maybe a new or fully cleaned and serviced rad. Now I just need to know what else may have gone wrong and how do I check for them??

Yep head gasket it is! Pulled the glow plugs out and there it is water on glow plug 2!
Thanks for the help simmo

Pull the water pump. It has a steel backing plate that's likely corroded. Cheap to replace last time I bought one ($20??).
The oil cooler might be another thing to check but I've no personal experience with that.

Hammer head, the old Isuzu was probably due for a "birthday" anyhow , new water pump, radiator clean out etc, she'll be good for another 200,000 kms

Ah well thank god the uncle in law is a mechanic, a few good words over the phone and a list of parts compiled and emailed off to various suppliers. now the waiting game of returned quotes and wishing it would stop raining here so i can start stripping the engine down.

thanks once again for your help

Don't forget to check the piston heights as it may well have bent a conrod due to hydraulic lock...😣😕.
