oh bother, 200tdi disco motor

NiteMare:
tootling home at around 55mph last night (10pm) and suddenly i heard a "thwack" and my engine died (big yellow taxi time  :sad: )...

no loud bangs or clattering just the "thwack", i suspect it was my cambelt snapped, immediately i dipped the clutch and coasted to a halt, torch under the bonnet and no evidence of damage externally ...

now not having worked on one of these engines before i need a little advice from the experienced for things/damage to look for/expect ...

i  believe i have to check the pushrods for bends (is it likely to have damaged any valves)  ??

i think i've heard talk of cam followers getting damaged, is it likely and how do i check ?? can they be changed without lifting the head ??

i need the quick and dirty answers to my fault finding and potential problem areas

this engine is in my old 88" (daily driver) so getting at everything is going to be easy enough (wings and grille will be removed) i just want to know what to look for before buying anything and making multiple bus trips for parts

all and any "knowledgeable" advice appreciated, generics are no help, i'm experienced enough with spanners so won't struggle with this i just need the "knowing" to advise

Thanks in advance

Saffy:
if it were me I'd first be looking through timing plug holes/inspection covers to try and see if belt intact or not. Removing rocker cover looking any signs of damage, see if engine rotated freely with spanner on crank (not forcing) see if rockers move.

im breaking a 200tdi so if you need the push rod set etc pm me

ChrisW70:
9 times out of 10 it will just bend a few of the push rods although it can snap one or some of the rocker arms. Not heard of it doing a follower before but there's always a first time.
Easy check is to take the oil filler cap off and get someone to flick the engine over so you can see if the rockers are moving or not, not likely to do any more damage as that would have happened when the belt went.

I'm only up the road from you, if you need anything picking up let me know.

NiteMare:
Thanks for the reassurance on the damage limitations Chris  :dance: fingers crossed that'll be all i find ...

also thanks for the offer of parts collection but i've managed to scrounge the loan of an LDV pickup for my shopping trip(s) so that's saved me a bit of hassle

i've a spare parts engine that i bought last year so if i've got anything broken/bent, with luck i'll be able to rob them from that one, ordered my cambelt and tensioners via a mate in the trade so should be collecting those about lunchtime ...

all i've got to do now is rig up a bit of a work shelter (canvas and scaff' poles) and crack on with the job...

finally if it turns out for the worst i can fall back on robbing the engine i have/had planned for going in my 109 when i build it

all i need now is for the sun to put in an appearance  :roll:  :lol:
