snapped crankshaft

[hughesrobert13]

Hi guys just stripped my mrs golf tdi 150 pd engine. It siezed for some unknown reason. First thing I done was removed no 4 end cap furthest from the oil pump. There was no damage at no 4. So I removed no 3 end cap once I removed it I could see that the bearings have spun and the crank have snapped. Any ideas what would have caused this. Cheers rob

Lack of oil would be my first thought

[hughesrobert13]

Its always had plenty of oil. And always the right oil. It had an engine rebuild around 20 thousand miles ago done buy a company that rebuilds engines. Im going to give them a ring first thing tomorrow. Il get the head off on the weekend and get the rest of the engine apart to see if I can find what when wrong. It just doesnt make sense

[Ash-Lee]

Even with the correct oil level there might not have been enough pressure.

If it's been rebuilt it could be a number of things, wrong sized bearings for a start etc etc.

EDIT : Allthough it has already survived 20K miles. Maybe something else gave up. I spun a shell on my 205 and that was oil starvation. Didn't notice until the red light came on but by then it was to late.

[hughesrobert13]

Surely if it was oil starvation the other bearings would be damaged. Maybe theres an underlying problem somewhere

Is it a turbo engine did it smoke could have hydrauliced all tho often just bends a conrod or put in 1st or reverse at high speed. again tho cank normaly ok if this is done

[hughesrobert13]

Yeah its a turbo lump. As soon as I get some time to strip it I will. Its my partners car and she doesnt drive it that hard to be fair

[danboi2]

why was it rebuilt in the first place? and was new or second hard parts used?

[hughesrobert13]

It had a very little knocking noise comeing from the engine that lead to destruction. It was rebuilt by an engineering firm through the garage we bought the car from. I know it had new rods, pistons, crank regrind, oil pump turbo water pump timing belt. It had loads done to be fair

A baffled sump wouldn't hurt for good measure, next time.

Shame, man. Sorry to hear that. I've been there with my old S13 200SX. No matter how many things I sorted out, another thing would break. The gear box was the final straw before I ended up breaking it.

My mate in work has a s13. I just fitted a welded diff to it be a right handfull when its bk on the road just shy of 300 horses. We avnt had many mechanical problems with the golf to be fair. Just the day she had it brake pedal when to the floor we had loads of electical problems with it then the engine blew up all within the first month of owning it then it was bumped several times had a new front bumper and headlights twice never anything serious. She parked it outside the house one day and didnt pull the handbrake up enough and it rolled down the street new tailgate bumpes and repair wheel well. And pretty much every time she drives it some one will pull out in front of you or nearly hit you. And its very rarely her fault im in the car with her most of the time and it is as if it is cursed. Weired I tell u lol
