wOw....Interesting event. My son and I used my old MKIII as a father son project when he was in his last year of school last year and we replaced some much needed parts on the 89 MKIII. Retorqued head, new gaskets, replaced the oil dumping CT-26 with a slightly used one that didn't dump oil into the intake.. Ok all good. Friday night he called me and asked to come get him. Said car was steaming and spewing coolant... Ha! Ok so I figured BHG right off the heezy.....Just like waiting for wifey to have the baby...
IT'S THAT TIME I thought.... since it was dark all I could was try to crank it and get it home...Skipping like a Kangaroo, I was only an 1/8 mile from home to begin with...got up enough speed to coast into the driveway. Felt like it was running on 3 cylinders.
The next Day.....
Spark plug valley was flooded with coolant, plug wires were shorting out was contributing to the terrible Misfiring..
LSS...compression tests show 125-125-0-120-120-115. Ok...so now I was gonna do leak down test (I just went through alllllll this a month ago with my Volvo 850 R) so removed the VCovers to see the cam lobes and used a long screwdriver to Feel Cyl#3 piston arrive at TDC...
PISTON DOESN'T MOVE....AT ALL!!...
There Is....
~
No oil in the Coolant
~
No Coolant in the oil
~ Possibly a bad radiator Cap which flooded the engine bay IMO.
~
NO broken hoses
Quicky....
Given that the engine was sprayed with coolant and he continued to drive with it backfiring and sputtering, could this backlash of engine jutter cause a rod to break???
Anyone ever encounter this? No loud engine noise, just skipping really bad, but #3 piston prolly has a broken rod or something. Engine Never knocked once on me. My son was driving it and had just gotten off the highway when this happened..NOw there's probablly more to the story but I'll never as hell know. But he's a mild mannered kid and babies this thing cause he doesn't want it to break cause now he has no transportation...
I will pull the oil sump one day this week to see just what is up, but Has anyone every encountered this problem before???? just curious. As usually a rod comes thru the block if it snaps in two. Sorry for the long post but Details speak volumes..
Incidently, my 850 R Smokes this thing...and it should be the other way around but Volvo is on a level that can't be explained....
Just to give you an idea of what the car looks like before and after,
