Nigel Triumph

As John says, your car is running rich. First simple checks would be the choke mechanism, either a sticking cable or the enrichment lever on the metering unit stuck partly open. If that's okay, the next suspect would be a vacuum leak on the inlet side causing the metering unit to deliver more fuel. Look for damaged vacuum hoses, inlet manifold gasket leaks or split metering unit diaphragm. If the above all check out okay, there's plenty more advice available here. Nigel

Rob, here's what American vets say about propylene glycol. Nigel

I've found data online starting the lethal dose of ethylene glycol for dogs is about 6mg/kg bodyweight. The equivalent figure for monopropylene was stated as 9mg/kg. Doesn't seem much of a reduction in toxicity to me. Animals accidentally drinking EG or MPG antifreeze will be seriously ill, possibly fatal, depending on the quantity ingested. I wonder at what concentration MPG is approved for food use. Is it approved as a good additive per se, or as a component of materials that may come into contact with food e.g. packaging materials? Nigel

Fernox seems to use monopropylene glycol as an antifreeze, replacing the ethylene glycol in blue antifreeze. Both are toxic, though monopropylene glycol is slightly less so (fatal dose for dogs about 2/3 of that for ethylene glycol). For me that's not enough reason to switch for ethylene glycol based antifreeze, which is widely available. Nigel

1972 was the year Triumph switched from imperial Type 16 calipers to metric, with the change in hole sizes. It causes confusion, as there's no exact commission number when the changeover occurred. Many have drilled out 3/16 holes to take a 1/4 inch retaining pin. The anti squeal shins are the same as fitted on my TR6. Nigel

That's what I thought too. Nigel

Good luck with your remaining classics. Hope you still pop in here from time to time. Nigel

Indeed! Nigel

+1 Private equity investors will be looking to extract value. Reducing competition in parts supply in this classic car market segment will enable them to do so. I would expect the following: - Cost savings by merging Moss and Rimmers' operations. - Leveraging of increased buying power to drive down prices paid to parts manufacturers. What effect would this have on quality? - Reduced competition on quality and retail pricing. On the plus side, the new larger combined organisation would have the financial muscle to invest in developing new parts.... If the owners se

+1 from me. I also agree with John. A glycol based coolant is fine for our engines and waterless is an unnecessary expense. Could it be there is some product placement happening on TV?? Nigel

I've recently fitted new old stock Trico arms and blades. The Tex items were not properly following the screen curvature on the driver's side. They seemed too rigid to comply to the profile of the screen. The Trico blades and arms work well, just as they did 50 years ago. They still turn up on eBay from time to time. Nigel

Not directly comparable, but could be a benchmark. I bought a Dolomite box with J-type for £450 about 2 years ago, and sold a GT6 box with D-type overdrive in good order for £400 last year. Nigel

4Life coolant is not waterless, basically it is water/glycol mix with extra additives to give long term corrosion protection. The waterless coolant is from Evans. Nigel

I've used 4Life coolant for more than 20 years and never had a problem with it, so I'm inclined to think the foaming problem is caused by something other than the coolant. The leak down test and lack of oil/coolant mixing suggests the head gasket is sealing okay. If it's not the coolant type, the thermostat or the head gasket, there are a few other possibilities to consider, albeit less likely: - A weak radiator pressure cap... Be nice if it's was that simple! - Excessive scaling of water passages in the engine, leading to localised hot spots that cause the coolant to boil. The
