Problem with me motor

[dave_s13]

Anyone on here know about diesel engines??

Basically my 405 TD had been using a fair bit of oil recently and this morning I took the oil filler cap off with the engine running and noticed it was blowing a lot of air out of the filler neck.

3 or 4 months ago it was losing coolant but that was sorted by bunging in some rad weld.
There were no puddles of coolant on drive etc, and everything seemed water tight, this seems to point
toward it being an internal leak somewhere??

Apart from that it sounds/runs fine and holds a steady 73-80deg running temp.

I'm thinking maybe the head gasket is fooked, whatdya reckon???

How clean is your oil? How clean is your coolant?

[dave_s13]

Don't know about the coolant but the oil is fairly mucky, I was going to change it this weekend.

What about worn rings?? would this cause the blowing?

And its an 'M' reg on 120k miles BTW.

[incorrigible]

Holed piston, dodgy rings, scratched bore, cracked liner, blown gasket can all have the effect of presurising the crankcase

All expensive to fix, and it won't fix itself

get rid

[dave_s13]

Oh bugger.

I've been told by a man in the know that it may be blocked breather pipework, a common thing on this engine apparantly.

If not then its up for sale.

Aren't cars bloody great, they have an uncanny knack of going tits up just when you least need it.

Let's face it, there's never a good time for a car to break!

Quite right Bonce but it looks like I'm losing me job in the next couple of weeks so its a right kick in the nads.
