Hi everyone.. can't say I'm exactly excited to be here - My mother and fathers 80s Series 1HD-T GXLs (Body 640xxx, Engine 100xxx) decided to go Kaput while I was taking it to the old workshop I did half of my apprenticeship in for a pink slip!!!
Engine has had extremely low oil pressure for months - despite my constant nagging about a diesel engines oil pressure it was not overhauled and eventually disaster has struck.
All started with my father making me put Engine Cleaner and Injector Cleaner through the motor. Ugh, was gut wrenching when I was doing it knowing what was going to happen but fathers know everything.
Anyway - I got 100m down the road after putting in the Injector Cleaner and heard a very noticeable tick / predetonation so I pulled over, wasn't coming from Crank Case but from the head - put it down to pre-det and kept driving, got another 50m and the tick completely went away and I was able to drive for the next 5km without any hickups. Cresting over a hill, the knock started to come back and only went away under acceleration.. Knock was getting louder and as I crested the hill I disengaged the clutch and let the vehicle coasts, this was the end of the line for the motor. Wouldn't rev match, sounded like I had lost 3 or more cyl and was hearing what I could have sworn sounded like a con rod bashing against the crank case over and over again. Turned the engine off (as it was still trying to idol, F**king tough bitch) and waited for the tow truck. 2hrs and a screaming match with a police officer later, I was on the way to taking the cruiser back to my temporary workshop I set up when things go wrong.
After taking the head cover off - everything looked fine other than the typical dirty sludge diesel engine oil protruding from every orifice. Grreeeeeeat I thought, onto the crank case. Now.. I haven't had the chance to vent my frustration yet so..
IT TOOK ME TWO F**KING DAYS TO GET THE SUMP PAN OFF! Hours and hours of slicing away at the RTV silicon gasket the wonderful Mechanics my parents took it to last time (who also forgot to do up a pully and snapped the brand new cam in our brand new head which is why I'm doing the work myself) - bashing the side of the pan with a hammer and a bit of wood with the small leverage I could get and eventually had to get a bottle jack, wedge the sucker between the chassis and the sump and just started cranking until I could hear the silicon starting to give way, TWO MORE FKING HOURS LATER the pan finally pops off and I observe what appears to be quite a healthy bottom end, but a multitude of metal shavings all the way through the pan.
My next job is replacing the oil pump which I haven't even looked at yet, I just got the pan off and called it quits for yesterday - but I did see heaps of fine metal shavings all the way through the oil pick up. I plan on uploading some high quality photos so you guys can tell me what you think, and any advice on this oil pump & anything else that is springing to your mind will be greatly appreciated as I've never worked on a 1HD-T before so I'm in the dark at the present!
Thank you guys in advance, AND DON'T EVER LET ANYONE WORK ON YOUR DIESEL!
