Title: Stat: can i refit this after putting cams back in?
Post by: Webby the Bear on 07 October 2013, 16:17:09
As above guys, i'm getting on it tonight and really going to crack on.

is there any problem with me fitting the cams, the rear belt cover, the cam sprockets and then fitting the stat.

the hose is currently flopped out of the way at the moment. but just want to get the cams in so i can fit the belt asap.

 :)

Yes you can. You need to put the thermostat in place then put some grease on the two o rings on the transfer pipe before sliding it in :y

ok, this is interesting...

new cambelt kit arrived today. Its a continental (contitech) like I purchased before but this time I got it from Northampton auto parts.

anyway, the last one, that went bang, had the old backing plate. not a problem as I simply swapped it over with the ''01'' backing plate that was on the car already.

HOWEVER just noticed how different the washer is in this kit (this is the correct ''01'' kit). this washer is smaller in diameter but a lot thicker (deeper). the washer from the ''EB'' kit had a larger diameter washer but thinner.

could this have been the issue that made it go bang?

Yes, it could.

The flanges on the idlers (gently) keep the belt in place. If one of the idlers is far enough out of position that the belt is hard up against the flange then it will eventually climb over the flange and get spat off. The same thing will happen if the idler is crooked (ie if the centre axis of the idler is not parallel to the crank, cams and other idlers).

Doesn't necessarily mean that was the cause though. Did you take any pictures of the strip down? Where was the belt when you took the cover off?

Were any of the pulleys siezed?

The rule with fitting a cambelt kit where the backing plate needs to be retained is that all the spacers must also be retained (its not like they are going to wear).

And have you not finished this yet?, I have seen continental drift move faster  ;D

iirc they were reluctant to move with the belt still on. but did in the end. i think.

hmmm, i think ill post some pics of what was on originally, what i fitted when it went boom and what ive got in the kit.... see what you ladies think :)

Hahaha yeah i agree i could have moved faster but sadly i didnt have the money to get all the bits. so got bits in order as i needed them.

however, rear cover and asprockets on tonight. then cambelt. then everything electrical which i'm dreading as its all a spaghetti mess :( then the cam covers. then the sandwich plate upwards. then the drivebelt.

AND WE'RE THERE! lol

i wonder how bad it will smoke after i start it up  ;D

Depends if you did anything to the heads....did you spit in the bores or put a drop of oil in them before the heads were fitted?

The EB backing plate is for the earlier v6 engines. Where for the lower idler (to the side of the water pump) there is a sticking out threaded section for the idler to sit on. On the later engine this protruding section is not there so the big washer is needed.
As to your question.... if on the earlier engine you did not fit the "washer" then the idler would tighten up against the back plate and wouldn't spin.
