Started taking the engine apart last night, heads been up my ass recently so I've only just started it again. I think the picture ive added on my desktop of my car when it was working has reminded me I do actually need to finish it.

Here goes...

Stripped it down some more today, is it me or are engines quite clean inside. I don't know if its me not knowing what an engines like inside or most of this is new.











Anyways I got the crank pully off and took the tentioner off went to undo the oil pump sprocket, head of the bolt came straight off without much pressure at all. Put it this way i could undo the thread remaining in the hole with my fingernail. That tells me that was loose to start with.

With a little bit more detective work, I stripped the oil pump down to find the following. (May be a sore sight to the trained eye)











From what I can see the cylinder thats sat insdide the oil pump has collected some metal from somehwere and scored the inside enough for the metal to build up and jam it together. Now I've put this down to be tightened up too much, now im not 100% on this because I'm unaware if anyone has ever even touched the oil pump.

So what I thinks happened is that its siezed up, the sprocket wasnt tight leaving some play for chain to rip the head off enough to spin without actually turning the oil pump. If that makes sense. It was all still intact when I opened it up, so the chains pulled the sprocket but rathern than spin the siezed oil pump its bent the head enough to spin freely without pulling the sprocket away from the oil pump completely.

I'm no better off now because I still need an oil pump but at least I think I know why it happened. Also I've learnt quite alot so far, and amazed a few friends that think I'm crazy for stripping the engine down. Just keep telling them its easy when you have instructions. :P

Good job they dont see this thread.

Cheers guys.

Hope you enjoy.
