Re: 2 alloy tubes under the oil filler plug?!

Martin, I removed them because I preferred the original arrangement. If the engine is worn and has more blow-by, it's not a bad idea to divert the fumes out of the engine bay.

Re: 2 alloy tubes under the oil filler plug?!

Martin, someone has added a pair of later 250GT diverters to your original breathers. It just funnels the fumes to the ground as opposed to allowing them to waft under the bonnet. My PF coupe had the same setup, which I removed.

Re: Progress on Brakes

Hi Martin, I am trying to follow what you are saying re the 3mm vs. 6mm. Are you referring to how far the seal stands above the cup? It looks more like 3mm here. Maybe you can explain. I got that elusive seal from Karp's a few years ago. I cannot remember the name of the fellow I spoke with. Inciden...

Re: Glass for rear window and ashtray for 250 GTE needed

Martin, look at the recent "330GT Console" thread. Pilkington has carcasses left from replica builds. They may have that window.

Re: Pedal box disassembly

Martin, there is no bimetallic contact here. The shaft goes thru three ball bearings and the cone itself is press fitted inside the pedal box. That is four sources of friction that you overcome in taking this thing apart. I think I modified a turnbuckle and placed it inside the box. There are specia...

Re: 250 Dimmer Switch rebuild

That's pretty brilliant, Tyler. You are right, the problem is not carbon but it's just contamination. This switch doesn't get much use so it collects dust, and then when you turn it you get dead spots. I gather that yours overcomes this problem by applying greater "wiping" pressure against the coil ...

Re: Pedal box disassembly

Martin, there is no place for a traditional puller. I seem to remember I fashioned an expander and placed it inside the box and then by turning it, I pushed out the cone from the box, which also pulled the shaft out. The diagram came from a pretty popular shop manual from the 1970's, it's titled Fer...

Re: Pedal box disassembly

Martin, I did this awhile back and I don't remember it to be particularly difficult. The main shaft is actually an integral part of the clutch pedal, which runs thru three ball bearings and the hollow brake pedal axle. The "cone" is press fitted inside the box. The first step is to remove the clutch...

Re: 250 Dimmer Switch rebuild

Please tell us what you did and how. These have a tendency to come unraveled in worst case and in best case they just get carboned up. Thanks.

Hi Andrew, hopefully this may be of help in sourcing the seals for the ZF box. Keep up the good work!

Re: Fixing oil leaks on the 250Ellena

Hi Tom, the 3.0 litre Colombo motors do not have a crank nose dampener, so the timing case is capped off. In this picture that cap is off and one can see how that screwdriver trick might do the job. But do you recall if that trick can be done with the motor in place? If so, did it require removing t...

Re: Fixing oil leaks on the 250Ellena

Good question, Ed. The risk here is the possibility of having the chain come off the crankshaft sprocket. Hopefully you'll get an educated answer. If not, I can envision also having to remove the right sprocket cover and use of a coat hanger wire. Good luck.

Re: Removing knock off spinners.....

Love mine. It's safe and effective, and light. Maybe a little expensive, but nothing out there is made to that quality.
