Yep, "Rolon" is DEFINITELY rubbish.

[trackerjack]

I have contacted Practical Classics magazine to further pressurise the problem.
Only by making waves will stop firms selling rubbish.

Maybe the club can source some and keep them in stock which in turn could save a lot of uncertainty over these useless Rolon ones which are crap

Yes we are doing that.

Sorry, didnt mean to sound so blunt, my son was screeching at me when I replied!!

All good

I did receive a reply from the vendor, eventually.
He said he'd been away on holidays and apologised for his late reply.
He thanked me for advising him of the problem, said he'd heard about it, but had no proof of it until now.
He asked me where I'd sourced the Jag tensioner and that he would investigate stocking it.
Cheers,
Rob

Ah f$$k. Ah these the ones rimmers sells? Just built my engine with a rimmers timing chain kit. Now I have to check what tensioner I have! Haha

[mikeybish]

Do we know for sure whether a larger or smaller oil hole is better? With a bit of web browsing I picked up the posting quoted below which would seem to imply that the "superior" Reynolds have the smaller hole.

"I do not agree with the above. I now have NOS tensioners in British Leyland boxes in front of me. The correct part # for the Healey is 37H7330. It does have the dowel and small oil pressure hole (about 1/32"). The MGB tensioner 12H3292 is identical except it has a 1/8" oil pressure hole. The latest issue from Jaguar is part # EAC3629 and has no dowel and small oil pressure hole. Moss lists this part # for the 3000 engine. I buy mine ten at a time from the Jaguar dealer and all have been Reynolds (France)tensioners"

There is another post in the same thread which seem to imply that the larger hole MGB type fail sooner?

Anyone got an genuine original to compare?

I have fitted a number of different bodies with decent pads and have had no issues - boss or no boss and big or small hole size.
As long as the pad stays on its ok...

It seems the pad only detaches on these rolons. and its been happening for a while. Aluns was the first we all knew about it but there
have sadly been many since...


Glad you took our advice Rob....

I just thought I would share my experience of re-setting my tensioner at the weekend in that as I removed the tensioner body from the block the spacer; 151277 neatly dropped off and into the sump.

it is not possible to remove the sump completley on the slant 4 but after draining the sump and removing the bolts I did get enough clearance to get my inside and find the part.

so cover that small opening over the sump pan before removing the tensioner.

When I found that the rubber had separated from the tensioner in my engine, I was glad of that opening.
I found the thing in the sump, and the opening made it easier for me to retrieve it.

Yes, I bought my timing chain kit from Robsport and sent them photos of the failure.
Through a series of emails, Simon asked me where I'd sourced the Jaguar item and said he'd make a few changes.
I'm pleased they have.
C'mon Rimmer Bros. (I sent them pics too)
Cheers,

Are these the same as fitted to the jag 4.2 straight six engine ?
If so I think I may have some tucked away ,
