200tdi seized I think

[rar110]

I bought a 200tdi wagon a few months back with bad blow by. I thought I would have ago at trying to fix the problem with a couple of doses of oil flush. 15 min into the second flush came a quick hammering type of tone from the motor. And before I could shut the motor down it went bang. And is now seized solid.

Here’s a pic of the blow by not long before it went bang.



Any suggestions about what let go?

Thanks.

Spun a bearing Drop the sump.

Big End bearing is my guess.

Thanks. The speedo indicates this Defender has low km for age. Why would a bearing go?

[jboot51]

Prime suspect, maybe the oil flush thinned the oil out too much.
Blocked filter from the flush actually doing its job, combined with the filter bypass not operating, if they have a bypass.

Just guess work really.

How many low k's on it

Choices are vast now.

300tdi

Thanks for suggestions.

This was 2nd flush. New Caltex oil and filter, & 1/2 dose of flush. I can’t recall km exactly but under 200k. Family is storing it for me so don’t have access right now.

Keep suggestions coming.

I have a perentie chassis/motor and new gearbox. So unless this is worth fixing the body will be going on the perentie. Will fit a turbo to the perentie while the body is off.

The blow by is a worry in itself for low k's.

With being low k but high age, maybe the timing belt has let go. Back the rockers off and see if it rotates. This would probably best case scenario.

[rar110]

Timing belt is a possibility. I don’t know if it’s ever been done. The PO didn’t know.

A timing belt break won’t seize the engine. The push rods bend instantly.

Time for a rebuild.
