Re: Post valve grind discoveries 1933 10/4

Hi All, latest and hopefully the last update: I received the Pistons and new rings back from my engineering outfit with newly cut slots in my STD pistons to fit the newer ( and slightly wider ) rings. All fitted to the engine using Jim Butterworths' system. No ring breakages thank goodness! Fitted t...

Re: Colwyn Top and Rear Hood Hinges and Spare mount

Regarding bumpers, single or dual blade. My 1933 10/4 has a single blade front and rear. I am told by other club member here in NZ that this was typical on export models along with 18 inch tyres It may be the the car imported to the US was a real 10/4 built for export by the factory.

Re: Post valve grind discoveries 1933 10/4

Thanks for the advice guys.
I have ordered a couple from club spares.
I did some small research to obtain some suitable felt in NZ but most is thin sheets 2 or 3mm thick designed for home craft use.
It is also all acrylic. So not suitable in a a hot oily environment I would think.
cheers

Re: Post valve grind discoveries 1933 10/4

Progress update. Newly made STD rings have arrived and I need to get the corresponding piston slots widened to fit. My mini Lathe is not up to this as I don't have the right cutting tool bits. The rings have been made slightly wider in thickness so the slots in the pistons can be enlarged to maintai...

Post valve grind discoveries 1933 10/4

As promised this is a new thread, hopefully not as long as the last one. After the valve grind I wasn’t happy with the compression measurements on cylinders 3 and 4. Decided to extract #4 while the car was still up on its stands. I have discovered I have 4 x ring pistons and the bottom oil scraper w...

Re: 1933 ten, valve grind

Thanks Bob. yes I agree, old cars/motorbikes etc consume oil. I have had a few over the years. However while I have the car up on stands I decided to check out the rings situation. I stripped the engine again and removed piston # 4. First thing noted was the poured metal big end bearing looked in fi...

Re: 1933 ten, valve grind

Thanks Simon,
Yes I suspect the next exercise will be a ring job. After the engine is warm there is some bluish smoke from the tail pipe.
Can’t be the valve guides as I have installed new ones and new ex valves!

Re: 1933 ten, valve grind

Update: Head back on and tightened down using the 8 “ ring spanner and sensing tightness by feel. Surprisingly I think I have all the nuts about right. I applied a small amount of copper grease to the stud threads and the nuts pulled up tight easily. The test for the success or otherwise of this who...

Re: 1933 ten, valve grind

Thanks for the replies and advice all.
Very much appreciated.
I will leave the torque wrench in its case and do it the traditional way by hand.
I have a set of suitable 8 inch ring scanners and plan to put the head back on later today.
Cheers
