Re: Jrr 929 d

The valve seats were re-cut and valves re-faced in 1992. Don't think its had any other engine work since.
Are you coming to Stoneleigh in it?

Re: Jrr 929 d

This evening I finished off the wiring and fitting of the Spitfire overdrive gearstick and replaced the passenger heater switch which was failing intermittently. Left of the three in this photo. Super fast deliver from Holden Vintage & Classic.

No idea if the overdrive works yet!

Re: Jrr 929 d

Another job ticked off. Windscreen.

I've been concerned that the screen moves around in the frame and wasn't 'edged' on the bottom, which it appears to have been in the past.

So I managed to unscrew the front mounts and tilt it back enough to get a a piece of 8x8x8 1mm think aluminium channel on the bottom. Just cut and bent to shape wrapped it some black insulation tape purely for cosmetic reasons and then and a squirt of Sikaflex EBT in it before pushing onto the bottom of the screen. While I was there filling the line of rivnut holes! Then gouged out as much of the hardened crumbly frame seal as possible before more Slikaflex to hold it in.

Now I just have to wait threee months to get the damn stuff of my fingers!

Re: Jrr 929 d

Thanks Ben. Yes it is s bit smoky, and knocking, so is in need of a re-build. Unfortunately whilst I have done a few rebuilds they are in the distant past and I no longer have the tools, time or funds to do it so I'll have to potter on slowly and hope it holds out!

I was wondering about updating to the later rocker cover cap and breather in the hope that would reduce fumes, what do you think about that idea?

Dont think it will make much difference just make sure the diaphram isnt split.

Re: Jrr 929 d

Hi David, My mistake your rocker filler cap is the correct one

so assuming the valve that also should be with the Mk1 2ltr. albeit slightly different design is working OK

The fumes are probably from a bit of piston blow by I think that engine was a bit tired when Doug and Liz had the car
don't think its had a rebuild recently.

The crankcase emission control valve on your engine has different cover design to normal Triumph but assuming it is working correctly, it is designed to provide a negative pressure in the crankcase. However your rocker cover filler cap is the earlier vented type so defeating any attempt to maintain a negative pressure in the crankcase. This may be adding to the oil burning but my guess is it would be the oil rings needing some exercise.

Also you have the binnacle switches and binnacles round the wrong way, the lights should be on the left so the dip symbol points down and not up.Indicators on the right side so down is right up is left.

I know too late now!!!!

Thanks Ben.

I spotted fumes coming from the rocker cover cap so had thought as much and considered ditching the valve. Annoyingly I removed a good valve from my prior Marlin as I put the later carbs on that take crankcase fumes into the carb bodes, then gave it away with the car! So I guess I should get the correct rocker cover cap and renew the valve?

The car is built around a MK1 2ltr, so I'm guessing the rocker cover cap is correct, and the emission control valve shouldn't be there anyway? Although the cover does have the take off pipe. I'll dig around Rimmers site for some guidance.

I realised the binnacle was switched left for right but that's how the wiring is setup for it from what I can see, and yes had noticed the new symbols were fairly useless! I'll have another look though.

At the moment I'm just trying to get it drivable whilst building a list of things I may have to revisit!

Re: Jrr 929 d

Todays work, apply new stickers for indicators and lights to the plastic steering column binnacle. fit the steering wheel using new screws and nylocks.

Test that the alternator is charging the battery as the ignition light is glowing, it is a good 14+ volts with full beam on. I suspect that's because it's been converted from dynamo but not an expert on that. Can I just ignore it?

I noticed the rocker cover/crankcase breather was flapping in the wind so repurposed a bracket I had from an old Vitesse I think with the bender so it's fixed to the manifold now as per production I think.

Re: Jrr 929 d

Thanks Ben, I have ordered that lock nut assuming it was sown in the wrong place on the diagram!

Good idea to secure the cable, I'll do that, thanks.

Re: Jrr 929 d



David the lock nut is like a threaded collarC30623 that sits inside the gear knob not where the
drawing here shows it.
Also secure the cable to the gear lever below the exit hole to stop it chaffing.

I speak like that all the time!! -- Think its an age thing ; - D)

Re: Jrr 929 d

Don't you love auto correct;

"a 'sling' walled lick nut "

Was supposed to be;

"slim walled lock nut"

LOL

You have been busy.

Finally! an update. Managed to get the Spitfire overdrive gearstick in place and re-bushed today. That means I have the wiring going through the hollow stick now, not squashed into the know and shorting out.

Bonus is that the clearance to the fuel line is now several inches, and the Spitfire stick is angled back more so shorty me will find it easier.

Had to drift out the reducer in the gear stick knob and open up with a round file to get it over the larger OD stick thread. Just need a 'sling' walled lick nut now, or continue to file down an old seat belt nut.

Re-connected the overdrive wiring and wired in the twin USB socked where the overdrive switch used to be.

Cover back on.
