Fizzy Posted January 10, 2011 Share Posted January 10, 2011 i seem to have an oil leak from the seal behind the pulley wheel, and while ive got the timing cover off i thought about replacing the chain and tensioner being as im already in that bit of the engine. ive no idea how old it is, ive not ventured into this bit of the engine before. its not making any untoward noises or anything, but i just thought as im there why not ? for 15 quid i can get the new seal, gasket, chain and tensioner so figured its worth doing.is there any reason not to though, before i pull it all apart ? would the sprocket need changing to go with the new chain ? anything i should look out for doing this job ?

Velocita Rosso Posted January 10, 2011 Share Posted January 10, 2011 Do you have leaks,rattly noise or problems with timing?If not drop an aspirin into the rocker and leave itIf you have the above symptoms then by all means ,if you have not or it has not been changed since Adam drove the car then do itHowever if it was me I would change sprockets aswell, as the old chain wil have worn them to its profile .OR, if you are spending money, get a Duplex vernier ,twin sprocket/chain for better adjustment etc Link to comment Share on other sites More sharing options...
drofgum Posted January 10, 2011 Share Posted January 10, 2011 Jason,I have chased the same leak on my Mk2 and I think you should examine the part of the pulley wheel that runs in the seal for a groove. If you find a groove your best chance for fixing the leak is a new pulley wheel, so, you might want to budget for the pulley wheel before the timing chain.

Velocita Rosso Posted January 10, 2011 Share Posted January 10, 2011 Correct, if you have a leak from the timing cover oil seal it could be the seal or as said a groove worn in the pully flangePulley`s are hard to come by that arn`t worn, so may be a good metal sprayer could do that job in a short time and then ground back to original diameterIf the oil leak happens to be the timing cover gasket then this goes back to an old thread of the bottom t/cover bolts stripping the alloy cross bracket on the c/caseIf you are taking the cover off then thats an ideal time to check that alloy block Link to comment Share on other sites More sharing options...
Fizzy Posted January 10, 2011 Author Share Posted January 10, 2011 thanks for the replies. im not having any undue trouble with timing or rattles etc - not from that part of the car anyway ;D ive had the car 3 years and its not been done, before that i have no idea. from what i know from the cars time with the previous owner, i'd say its at least 5 years old if the owner before him changed it. so basically no idea of the age of the chain. im keeping costs down to wont be duplexing. the only leaks the engine has is from the well known rear corner of the block/head and this new leak from the pulley area. its definitely not coming from the gasket. i will examine the pulley when its apart. i hope not though, its my only car and i was hoping to just replace the seal and get the job done.

Steve Cureton Posted January 10, 2011 Share Posted January 10, 2011 I don't like oil leaks, especially ones that throw oil everywhere, so as it's a relatively easy job so I would just do it. The screws are different lengths so just be careful to replace them correctly and don't over-tighten the ones that screw in to the alloy block at the bottom.

Fizzy Posted January 10, 2011 Author Share Posted January 10, 2011 it will definitely be done, minimum of seal and gasket. not sure what i'll do if the pulley is scoreed, i dont know where id go to get it sorted. thanks for teh info about the screws, wasnt aware they are different lengths.fortunately i get my oil for free, so at least its not costing me anything while its dripping out ;D Link to comment Share on other sites More sharing options...
AndyV Posted January 10, 2011 Share Posted January 10, 2011 If you do have a groove in the pulley, no need to renew it just put a couple of extra shims behind it to move the part the seal runs on. A 'V' fanbelt will tolerate a tiny bit of mis-alignment (or a spacer in the timing cover to move the seal back a mm will do the same).I have an alloy pulley and do the aboveAndy Link to comment Share on other sites More sharing options...
Hogie Posted January 10, 2011 Share Posted January 10, 2011 If the pulley is worn where the seal sits there are some sleeves that can be slid over the pulley shaft. They are very thin and give a good sealing surface.Not sure who does them or what sizes but others have commented on them. Much cheaper than metal spray if obtainable.Rogerwww.acorn-ind.co.uk/products/speedi-sleeve try this for speedi-sleeves many different sizes.

rhodes Posted January 10, 2011 Share Posted January 10, 2011 Presumably the next episode of this thread will deal with the saga of undoing the crank pulley nut? Link to comment Share on other sites More sharing options...
Fizzy Posted January 10, 2011 Author Share Posted January 10, 2011 haha, i forgot about that. if im lucky it will be held together as loosely as the rest of the car ;D ;D ;D Link to comment Share on other sites More sharing options...
drofgum Posted January 10, 2011 Share Posted January 10, 2011 Jason,The sleeves that Hogie mentioned are available from SKF as Speedi Sleeve or something to that effect. There may be other suppliers. The problem with them is finding a stockist who will sell the one you need rather than, say, ten of a size. Best of luck, Paul Link to comment Share on other sites More sharing options...
uksnatcher Posted January 11, 2011 Share Posted January 11, 2011 Just done c/shaft pulley seal on my 1500, the old seal was the 'cheaper' type , lucky i had no groove in pulley just poor single seal lip rubber that had gone hard in 6 months causing a drip when i parked up.I replaced with, and can highly recommend a 'Payen' branded seal, double seal lips and quality rubber and springs, bit more expensive but does wht its suppose to very well (£6.50 delivered ebay) Link to comment Share on other sites More sharing options...

Better quality seals may cost more but they save a lot of duplicate time and effort. Link to comment Share on other sites More sharing options...

CHRIS211083 Posted January 16, 2011 Share Posted January 16, 2011 Well it will only sit here other wise. I was going to rebuild my own motor but had three operations and that kind of cancelled it. So i got it built by Chic Doig, this left me with some spares that i had saved up to do my rebuild my self so he's welcome too them. Im sure people would help me out on here if i ever got stuck, just repaying the favourChris. Link to comment Share on other sites More sharing options...
