After months of wondering should I do it or trade in my beloved 155. the tensioner pulley decided for me.

Took my head with it obviously, dont know the extent of the damage but I can only assume all 16 valve are bent, after I tried starting it a couple of times and the RAC man asked to turn the engine over to listen.

Anyway what I could do with is general tips from you guys.
If you can help with how much parts are, I've been told that the head gasket set is £150, is this right?, also what exactly is the variator and what bits of it wear out and what would need replacing.

I'm glas I've managed to sort out an interim car, so I can do this at my leisure.

Any help would be appreciated

Many thanks

BTW I'm sorry I've not been on the forums recently but Ive been busy on Unreal Tournament, how sad it that!!!!

Dayco Cam Belt £22.62 ,Dayco Balancer shaft Belt £16.32 .

Good luck

I saw an ad recently that had replacement re-con engines for 155's roughly about £700-1500 for 1.8 8v - 2.5 v6. It might be worth doing it like that & get a whole new engine!

Sorry to hear about this lespix, I live in constant fear of that happening as it happened to me on my last car (Escort) and was a real hassle.

I would be interested to know how many miles have been done since the last belt change (or since new if applicable) as the recommended interval is blatantly optimistic eek!

Hi BW, the head on my car was actually rebuilt about two years ago (less than 16,000 miles), it wasnt the cambelt that was the problem but the tensioner, my advice would be if your thinking about changing that tensioner pulley, stop thinking and get it done!!

I believe it costs round about £300 to get it done compared to £1500 for a rebuild.

LOL

I know the tensioner is usually the culprit, and had everything changed not long ago (~5k miles) and had the belt checked about 1k ago so should be ok for a while, I was just wondering at what mileage it had failed - you say 16000!! eek!

It seems to me this job needs doing probably every year/12000 miles. Mine will be changed again at the 60k service, which is only 3k away. I wonder how many people who don't use the forum try and change them at the stated 60k and actually get away with it?? If any frown

Hi my 96 2.0sportpack at 34000 miles did the same [i talked about it on the old 155 site]cost about £1700 2 years ago with a main agent it did most of the valves pistons ok but had the head skimmed and had new seats put in at the same time
the belts at 34000 looked ok i think would have been okay for quite a bit longer ,the tensioner seems to cause more trouble than the belts,hope the modded one lasts okay?
If you repair your engine i would advise a new water pump at the same time [behind the belts]if you are going to keep the car.my car only gets used at the weekends so it has only 40000 on the clock now ,so i should be ok for quite a bit longer.
Good luck.......

Regards Graham

Second hand head should be cheaper, I'm such a fair bloke that I sold the one off my car for £250 complete with everything, cams, valves etc so if you can find another at that price then its not much more than a set of new valves.

Failing that, the latest AROC magazine has a GTV 2 litre 16v engine advertised for £500, don't know what year though.

Hi all, managed to strip the ancilliaries and got a look at the culprit.



Does anyone know how to get the inlet manifold off once you've got the nuts off!!

BTW is this pulley supposed to have black plastic around??!! Also the belt managed to get the wrong side of the pulley (God only knows).

Haven't got the head off yet I still need the special tool (RIBES), anyone know where to get them as I don't think there gonna be in the local Halfords!!

Thanx for all your help and ideas guys, I'll keep you posted once I've got the head off.

BTW Nordic I'm from (Sunny) Bolton.

Regards

My 16v has covered 96 k miles now with one belt change at 60 k, maybe before the supercharger gets fitted i should get these bits changed... personally i dont agree with this idea that the 16v engine is fragile, mine isnt... hes says gripping a piece of wood :)

you can leave the manifold in place it doesnt need to come out..halfords may well do the head bolt tool.

Hi all, got the head off and surveyed the damage.

BTW i'm in the process of writing this stuff on web pages as commentary of the work, hopefully this'll help others as i've included special tool pix and other general info, I hope it'll help, anyway . . .

It seems that the inlet valves are totally bent and may have pulled the guides down with them, some piston damage but not severe, just scoring (don't fancy bottom end rebuld!!)

Exhaust valves look fine but who am I to say, cams look okay, but no way to tell until it goes to engineers shop as I don't have the tools or the know how.

Ill keep you posted

Cheers

Sorry to hear of ur misfortune lespix.

I'm getting my belts/pulleys/tensioners/variator done soon as im reaching 56k (well no not
me, the car...). My bro (jase77) bought the head locking tools and he finished doing his
the other day (his 2nd time of doing this) so i feel im in good hands.

Don't know why some Twin Spark engines last forever and some barely reach the end of the
street - Alfa's eh, who'd have one.

- Honkytonk.

the tensioner seems to cause more trouble than the belts,hope the modded one lasts okay?
I saw comparitive pics of the original & 'modded' tensioners I think on Henry Yorke's site. Was the modded one fitted to the later cars or did they all come out of the factory with the original tensioner and the modded one was only available after the 155 stopped production?

Anyone know?

One other thing, someone on the forum mentioned that Gonella brothers over in E London would do the cambelt job for around £200.

Anyone know anything about them and whether this includes all the parts?

Far as I know the 155's were all fitted with the "old" variator. Advice is to fit the uprated part. Later 156's don't have the problem, earlier ones did, up to about year 2000 I think.
