Greg,
The Jaguar part number for those copper cam oil banjo bolt washers is C4146 but that wonât help you. I believe that John_John machines his banjo bolts differently than the Jaguar and uses much thicker copper washers incompatible with the original Jaguar banjo bolts. You are probably best off finding out what John_John uses.
This is one reason that I am reluctant to use his banjo bolts.
I finally found some on Amazon. 16mmx10mm seems to be more the more common size you can find. But I think Jonahâs have a slightly bigger bolt head mating surface, so 18mm OD is warranted.
He sells out of those banjo bolts very fast. Popular item!
LOL @ âHorror Freightâ, Wiggler ⌠Reminds me of how I call our local place Northern Foolinâ Supply ⌠I go in there thinking Iâm going to get something for a reasonable price and am always astounded when I go to look at the price tag and find out how much theyâre asking for it âŚ
Grease doesnât melt copper washers. They always turn silver when heated. If you annealed it it is now soft and will deform to make a good seal so it does not have to be totally flat. If it actually melted beyond repair you have overheated the washer which you do once so you forever know how much is to much.
Greg,
You can try to sand it with fine sand paper in a flat surface, it has plenty of thickness.
Anneal it again after, and as David said, it will be soft enough to deform and make a good seal.
An other trick is to use washers with a slightly larger ID and put a small o-ring in the gap. Works very well.
If you have a FLAPS nearby that sells âDormanâ parts, look for Dorman brake hose bolt washers, P/no 66250. They fit the banjo bolt over the radiator, and are the right size for the cam oil feed also.
Go easy on the heat next time!
I was told a propane torch could not provide enough heat to melt copper, and i got all washers to glowing red for about the same time. In fact, a few i did even longer, and no melting.
Greg, i had a similar experience with what could be as you describeâŚa dud washer. I had mine suspended using a screwdriver shank through the hole. As it got red hot it started to droop elongating the hole. From China.
I never have had a problem re-annealing those on the car. Jaguar parts. Maybe from a better Chinese factory
They donât need to glow bright red and they donât need to for a while⌠they just have to get hot enough. If itâs dark and you can just barely see a faint glow thatâs enough, you can quench them or let them air cool and theyâre softâŚ
Of course propane melts copper washersâŚ
Tighten them a bit more
Or sand them down. No it wonât make a difference. If you look at the diameter of the drilling in the bolt you can see for yourself.
Thanks. Also, I only heated the washers up until they just started to glow a dark orange before quenching them, compared to me getting them bright orange before.
No issues this time, and I noticed they oxidize way less.
