Engine blew on my Combo 1.7di van last week.

£750 + vat for replacement + fitting etc.

Doubt if there will be any change from £1500.

Weeks'  work lost also.

It's a never ending struggle!

1)  I thought everyone knew about timing belts and the need to replace them regularly?  

2) When will more manufacturers be like Subaru and make engines that don't totally self destruct if the belt goes, or be like some VW engines which have gone back to a much more reliable timing CHAIN?

 
Oil pump went on my combo. That drives the timing chain. Got away with it! Had that repaired and then the clutch went. Sheared the bolts holding the thrust plate, which then dropped into the sump..... wasn't so lucky that time.....

Got that repaired.....now wondering when the whistle from the turbo is going to be a problem.

I could have replaced the van with the ammount I've spent on it this year....still I suppose all the expensive bits have been done now.

 
Binky is quite right;  Just unfortunate that an elastic band

is the ONLY way to drive the overhead cam shaft on engines

like these BECAUSE the belt needs no lubrication.

 
it's just cheap nasty engineering, but bloody expensive when it goes wrong, which is what is so annoying. I had a Norton Rotary motorcycle with the chain fully enclosed and running in a bit of oil. Chain lasted forever, only needed adjusting with a new tyre, and when feeling guilty cos it hadn't been adjusted for about a year. Main thing enclosure did was keep dirt and water out so chain got easy life. Wouldn't be hard to do something similar on a car, though I would prefer it to be built into the engine itself and gear driven.

 
Inclusion of a gear train for a drive lengthens the engine;  space

is at a premium between the front struts.  When the clutch was

done on my engine, the whole front end suspension had to be

dropped.  The bell housing could not be swung out to permit a

renewal.

 
Im with Binky on this. If Honda can do gear driven cams on their bike engines, then they can do it on car engines too

to the OP, £750 for a new motor? I recently had to pay that just for a bloody gearbox :(

 
Oddly enough, a lot of the early motor vehicle engines

had overhead camshafts.  The camshaft was located

as it was with an internal chain drive only because it

was difficult at the time to lubricate the drive for the cam.

So Pro Dave's motor was/is a major advance.

Yer, the Honda V4s (NCs , RCs etc) have gear driven cams and pretty bullet proof enginges,

But the gears make it a nightmare to tune having to shim cam seats and resize valve stems etc. headbang
