That white gunk looks suspiciously like oil/coolant emulsification from when it was running coolant - not sure but I don't like seeing it where it is. I am concerned about the rusted condition of the coolant galleys in both head and block. Not sure how best to treat that short of a full tear down. If the water pump is hard to spin then that might be a sign of a bad or going bad bearing. Investigate that now. I am going to ask the innocent question - how will you clean the block top surface so that debris does not fall in the cylinders or cooling galleys or oil galleys? @JohnCh Beer money bet - how many cylinders do you think were breached?

Correct. The Caterham will have a J1962 plug which looks like OBD2 but it is not. The stock Caterham ECU produces CAN data format but does not produce OBD2 readable data and never will. So no OBD2 scanner will ever read it. So if the DMV wishes to test emissions it will need to do it via tailpipe sensor. Easimap will let you "read" the data from the ECU real time but will not let you modify it as it is locked with a password. Anyway, a replica or kit car approach to registration in VT should allow you to bypass this. Ask how a Cobra replica would go through the process - you would need to follow their approach. P2226 error code is exactly as you found it on L7C. To remove it you need the SBD upgrade kit for a separate sensor - they will be able to confirm in a phone call. That will just make it run a little better but its unlikely you would notice the difference. May have an emissions impact though.

How many gallons is that new tank? Does the bag completely fill the metal housing when full?

Fiberglass gives spider cracks from the stones hitting underneath or on top. Not much you can do about it as it just happens. Film or no film, spider cracks happen. What some people have done is coat the underneath of their fiberglass wings in truck bed liner. Stops the stone hit transmitting through to the top surface, unless it is a really big stone.

Just for those who may not normally browse the classifieds - I thought this nose cone demonstrated a rather unique perspective one does not always see on a Se7en. I am used to seeing headlights out the front of my car but this is an interesting variation. From here if you want to see the full ad: LocostUSA.com • View topic - MCC 7 for sale

A genuine 1981 chassis will be imperial. Changeover to metric occurred post 2000 sometime. If you want I can check your chassis number to be sure, as year of chassis should be coded in that - PM me with it. The recent leather seats are called "S Type" seats. Assuming this is what you mean? Photo shows it missing headrest. For the Caterhams with the two individual seats, they have bonded three-sided aluminum channels under the floor to provide floor rigidity for the seat mounting point - 4 of them running longitudinally. The seat frame then bolts through these. So you would need these. Inquiry of Caterham may be able to source them otherwise you would need to fabricate here. For seats, there are two types, the S3 type and the S5/SV type. SV type are a little wider. Going off the top of my head the width was an extra 1.5 inch between the 2 versions. The S3 width should fit your imperial chassis, as the size variations were minimal but noticeable, but you need someone on here with a recent S3 build to measure their seats to confirm width of seating tub area and width of seat just to be sure. I have an SV chassis so cannot help here. Lowered floor is an option on Caterhams - both chassis types of S3 and SV. I just checked the parts site and I can see they have imperial chassis lowered floors for an SV. You would need to ask Caterham if they can supply a lowered floor for a pre-long cockpit imperial S3 chassis and before purchasing confirm with them it will work for your car. Lowered cockpits came in on the long cockpit imperial S3 chassis and were then modified in the conversion to metric. Caterham may not make one. In which case you would need to fabricate. One question, I do not have the answer for is whether the lowered floors still use the three-sided channels for seat mounting? I cannot recall and it may not be needed as the lowered floor shape may offer sufficient rigidity for the seats to mount safely. A lower floor installation is just a removal of the existing ali panel floor rivets on the two floors (driver and passenger), remove and then apply new lowered floor and rivet. As to whether this is easy to do is subject to opinion but I am sure a good race workshop would have no problem installing both the seats and the lowered floors if you decide you don't want to try.

@PokeyI get those black marks but the solution is use WD40 and then give a soap and water wash afterwards so no WD40 remains.

@kayentaskierNot at all - 5am - normal time for me to get stuff done. I had a busy day at the beach planned....

@kayentaskier Thats exactly how I did it. I had the carbon fiber wings and just did the 3M film over the top. No stone guards. Its lasted 10 years although could do with a reapplication of the 3M film looking at it today. I think I still have the original Caterham carbon stone guards that came with the CSR in my garage - never installed them.

@JBH And still a very quick car! @Vovchandr Yes we read your threads - look at view count.

@Bruce K Come on Bruce - your wife is quicker than you!

Burnishing is wear. If it appears on the camshaft surface then it will be worse on the tappet surfaces (for the Zetec) as they are usually softer metal. Interestingly the burnish marks are not even across the face so that tells me something was not evenly aligned or machined correctly. When you have disassembled completely you will be able to do a proper close inspection of the marks and see if any surface pitting exists on the camshaft (which would not be a good thing). I would expect the tappets will need replacing if that truly is burnishing on the camshaft.

No that could have been where the head had been skimmed too much as it is an old reused POS and you needed the extra gasket to get to a compression result. I have done that with Holden engines back in the days when I was young and stupid.... ...since then I have gained much experience on why that may not be a good idea.

Thats great news Jeff! Which track were you running?

@Lucky-7 What year is your car please? If 2013 or later then the photo @Vovchandr really needs is of your AP front hub and mounting point for the stay for front wing so he can compare that to his. Your wing stay lower mount point and front hub should be different to his as the manufacturer changed over time.

For the record, you convinced me there was a problem with your combustion process in your temperature scans on June 21. I wish it convinced you at the time. That cat converter was hotter than the sun. A single cold exhaust header tells me unburned fuel is making its way out of the engine and then combusting in the exhaust/catalytic converter. Cat converters are really expensive to replace - don't damage the one you have. Your car has more problems than a Republican politician found in bed with a dead girl or live boy (with apologies to Gov. Edwin Edwards who died this week).

@birkinsuper7 I like the way you roll! May you have many more happy miles.

Thanks @fastg and @papak

@Kitcat Yes it was a Caterham 6 speed. Now I suspect it is a metal casing full of shredded metal based on the many expensive noises it makes when you try to rotate the wheels. Very little warning sign - I changed down from 4th to 3rd and felt the change be slightly unusual - stiffer and shorter than normal in my hand, no noise indicator. I was sensitive to gear changes because I had been shaking down the Holden in the previous session to decipher its gear change issues and evaluate suspension set up changes. So I backed off the speed immediately and was planning to come to the pits to check it out. I made it another 500 feet before it all locked up and I did a Kitcat-quality tank slapper. Fluid in gearbox was fresh and at right level. No leaks or prior issues. Changes felt clean and normal right up to the last one which is where I sensed a problem. Clutch is a year old and feels normal, even after breaking the box. I could still select gears cleanly with engine on stationary with clutch depressed so assume its output shaft area thats broken. It was very sudden. Its 11 years old and 10,000 miles, most of that on track. So with that perspective maybe not a surprise. Replacement box secured and the old one will be rebuilt. These things happen

@fastg I agree - CMP is a very promising track. Freshly resurfaced too. The message from Steve was that it suits se7ens well now. @Kitcat Sadly I will now not be making the August option at CMP and it will probably not go ahead[. I had an expensive day yesterday when my gearbox blew up on track. It locked up solid throwing me rather violently into your special grassy regular parking spot at Thunderbolt at the Devil/Octopus. I thought of you while sitting there waiting for them to stop the track and recover me.

@papak Education time for me please - whats a "Nord-Lock" washer?
