I fitted a new set of pads that squealed. Another new set of a different make cured the squeal.

DVLA can become confused sometimes. My 4A is 1966. USA registration 1967. Given F reg. This had already happened when I bought the car. I would speak to them before submitting paperwork.

Had something similar on a Ford Escort. All new components. Slight brake pull in the dry. A lot worse in the wet. Turned out to be unmatched discs with different coefficients of friction.

It's use was demonstrated at the TRGB engine building seminar the other weekend. Very impressive.

I think the inference was that it had not been recognized that there was a restriction, just inadequate oil supply.

Hi All,
Just did a full engine rebuild and wondering if there is too much oil going to the rockers. This then collects in the PCV and flows back into the intake.
Observation one is that the valve cover baffle is a bit makeshift, so have made some simple drain modifications there. The other is maybe there is excess oil reaching
the rockers and misting. At this point It is likely too soon to subscribe to the "remove PCV and use draft tube" solution.
So am wondering how many folk use an oil restrictor under the pedestal? Was the external oil feed a competition alternative or a lack of oil solution?
Cheers,
Alf
At Saturdays engine seminar at TRGB Gary /Jason mentioned that there was more than enough oil supplied to the rockers without modification. The only times they came across an external oil feed was if the rear oil gallery supplying the rockers had become restricted and the external oil feed fitted as a cure.

Thanks Tom. I think I've ordered them but did not have to pay! A very confusing website. Maybe they'll email me back tomorrow for payment.

Has anybody used the Bastuck syncro rings and how would they rate them.
Thanks

Oh know It doesn't. Well it does actually... https://www.ebay.co.uk/itm/41-British-Made-Second-Imperial-Hand-Tap-Tapping-Drill-5-8-x-13-Thread/371848536866?hash=item5693e66322:g:DagAAOSwpDdU-IXe

I had the same problem so used some R10 rubber extrusion from Woolies. Page 19 of their catalogue. Allows the vent lid to sit flush and seems to seal fine.

Hello Alan,
Please see my (earlier) post entitled TR4A IRS AXLE NUMBERS - I wonder if you could please provide your car's build date and (approx if you prefer) chassis number to help my table?
Many thanks
Tony
Build Date 19/09/66. Chassis No. CTC 73477 L. Eng. No. CT 73602 E. Diff. No. CTC 66298. LHD US Export IRS car.

Had exactly the same issue. O/s spigot rusted solid. Heat and extreme violence applied from below eventually freed it but thread was destroyed even with nut being left on. A right bar steward.

Hi John,
My 4A diff is marked CTC 66298.

I'd bet on the pulley too -- good idea, Bob. Those things can make an awful mechanical racket when they're wobbling just a little bit.
I'll double check the pulley in the morning. Thanks guys.

What "deck height" are you running ?

Hi Mark,
No idea I'm afraid. I did rework the head a couple of years ago but did not have it skimmed. I refitted it with a standard gasket.

The reason for this question is that my 4A engine suddenly made a loud clattering engine speed related noise which disappeared after a couple of minutes and did not return during careful 40mph drive home. Thought it was the chain tensioner at first but this has been ruled out. Also removed sump but nothing suspicious found and no visible damage to valve gear. So I wondered if a sticking valve could have hit a piston. But I thought this could not happen on TR 4 pot engine. Hence my question. I have ordered a wifi endoscope and will look for any damage to a piston anyway and will do a compression check soon as I can collect the tester from a fellow club member.

I had always thought the TR 4 pot was a non-interference engine. Is that correct?
Alan.

Thanks for the replies folks. Water pump, heater fan, dynamo rev counter and rocker cover all appear ok. As there is no mystery noise at the moment I will continue to drive it. Hopefully it won't happen again but if it does maybe there will more clues to diagnose the problem.

During our latest TR run my 4A suddenly starting making a noise that sounded like the fan catching something. It's an electric fan that wasn't running so that was ruled out. The noise was defo engine speed related and increased with an increase of revs. Took the rocker cover off, thinking a tappet problem but nothing appeared wrong. The noise then disappeared. Drove the car home, 25miles, with no noise or any problems. Oil and temp were fine. At home have removed the timing chain cover, the sump and the plate at the bottom of the bell housing. with nothing untoward found. Gearbox oil was also clear of any debris. Any ideas what the cause of the noise may have been and what to do next?

Interestingly? if you input the reg. no. in here https://www.gov.uk/check-mot-history it comes up with the car it's on. I think previously you had to input the car make as well.

I support and lower the diff on a sand bag and trolley jack. Works well.

BRAKE SQUEAL

Hi Roger,
Some squeal may be caused as you say but the pad friction material can and as in my case does cause it as well.
