200tdi Rebuild

(1/2) > >>

MTyrrell:
The 110 has acquired a taste for oil rather than diesel.  I changed the head gasket hoping it was the cause. When the the old gasket was removed it was showing signs of leaking, so i was pretty sure that this was cause of the oil consumption and didn't look any further.
 
 This didn't solve the problem :-(. After stripping the engine down again it it looks like the rings have gone, there's a lot of carbon build up below the rings on all pistons. Also the big end shells are warn down to the bronze colour metal.

 I'm probably wrong, but i always thought the 200tdi is good for several hundred thousand miles with out any major maintenance. So is this sort of ware a sign that the engine has been poorly maintained, thrashed or generally had a hard life?

 Also whilst i have it in bits is there anything else worth checking or replacing? Currently i'm only replacing the rings and big end shells.

Thanks
Matt

 Thanks, what's the score with the oil pump can it be rebuilt or is it better to replace the whole unit, I'm not entirely sure how it works.

of the top of my head a new pump is £40 & id personally wouldnt bother trying to rebuild it,just fire a new pump in,

ive been down the road of a recon engine fitted with the original oil pump,queue a <EDITED> engine cos the oil pump had masses of wear

unknownmanxman:
While you've got the engine in bits you might as well stick a new oil pump in, they're cheap and its easier to put it in now rather than lying under ur landy with oil dripping on you replacing it in a few months!

Regular oil changes seem to get on well with TDi's
