Kv6 oil seals

Lates · 25th January 2007, 19:20

Evening gents.
I need to inform you all with the KV6 engine that I have now come across two of these engines which have decided to "let go" the front cam shaft oil seal blanking caps.

One of which is a member on here who with a pretty new aged,low mileage ZT with no history of engine works.Spotted purely by luck after going under the bonnet to connect pad wiring.
One we have seen failed 5 weeks after the belts have been replaced.A local dealer refitted a new seal twice now and both have fallen out again.I am awaiting feedback to let you guys know if there is a solution.

I am not telling you guys to cause any concerns, just be observant when mooching about under the bonnet, as I have not found the root cause as of yet.

Thanks Lates, I am not looking under my bonnet I'm much too scared, there's an engine and all sorts of other complicated stuff in there.

Nutter,!! the offending seal is below the PAS bottle and near the radiator if any peeps need a hand to find it.

Evenin Dave,
Good to hear your Zed is all ok. Bit miffed as to why this car has thrown out 3 in total, one of which we put in and the dealer the other two.

Daft as a brush yes, Barking mad no.
I always have a look under the front whenever I'm parked on some clean tarmac. As long as there are two small puddles of fresh water I'll be happy, anything else will be investigated immediately.
One of the things that does concern me is having the underbelly shield, that can catch leaking fluids and mask any potential problem for a while.

I'll be out under the bonnet tomorrow scrutinizing every nook and cranny now.

Thanks

My experience with oil seals blowing out is related to industrial gearboxes and pressure build up as it warms up and not being able to vent because of a blocked breather.

Thinking about this, if the car is low mileage, is it possible there is a sludge problem in the breather pipes, which as we know are very small bore, and in this weather, and standing around, oil sludging is a problem especially on cheaper semi-synthetic oils.

I can see the theory behind the pressure build up.None of the vehicles have any outward signs of poor breathing tbh. Will keep you guys posted on any information gained.
