Timing / Cam Belt change
It’s been too long since changing the cam/timing belt on the M20. It's nowhere near the mileage limit but it's far too many years overdue. I ordered a new Contitech...
Fuel filters and one way valve
The fuel filter elements are the originals from 2005, so it was time to change them. The good thing Sytec still make the bullet filters and the elements are available...
Fuel Injector Rebuild
In 2005 when we build the car we had the fuel injectors out, added new o-rings and gave them run in an ultrasonic cleaner. They are now 33 years old...
Oil Filter Housing Plug Replacement
The M20 engine leaks oil, this is one of the places it started leaking from recently. The housing which the oil filter connects to and the oil cooler pipes has...
Coolant Expansion Tank
Purchased a new coolant expansion / header tank to replace the original 1988 part from the donor car. For the first time since building the car you can see the...
Radiator Return Pipe
Since the car was built the return radiator hose as been a long flexi pipe, this was never a good solution. At some points the pipe rubs which eventually would...
Varex Exhaust Video
Had a chance to record some new footage of the exhaust. XForce Varex VMK51-250 variable volume exhaust - it's pretty much straight through when it is open. Here's a few...
Water leek, from back of the head
Another week, another new fluid all over the floor! Coolant this time from the rear port on the cylinder head. That's the pipe that goes to the interior heater core:...
Fuel pipe refresh, car pee’d all over the floor!
Car pee'd on the floor... It's a bit drippy here at the back, but also at the front on to the start motor - not overly safe and smelled pretty...
Coolant flush and refresh
This drain plug has been leaking forever, the drain part is reverse thread and normal thread into the radiator. The thread into the radiator needed more PTFE. Due to topping...
Varex exhaust build part 5
Video (obligatory no exhaust clip right at the end when everthing was off): https://youtu.be/KXJBKerTiNI
Varex exhaust build part 3
Built the other side of the exhaust today. Welding is 'better' than when I started but still pretty uneven. I can't weld too far consistently around the curve yet. Did...
Varex exhaust build part 2
Step 14: Cut down the output pipes, otherwise the tips would stick out too far. Step 15: Tip test fit, could move these back further by cutting the tip input...
Varex exhaust build part 1
Progress on building the new exhaust. The welds a'it purdy but they're solid and not tea bag considering I've never used a TIG before and have learned how to use...
Exhaust design v2
A little bit of an optimisation, someday soon I may get around to start building it.
Exhaust tech drawing
Plan for the updated exhaust, straight pipes shown full length and relative spacing is not correct.
Some new exhaust bits
Planning an update to the exhaust, starting early in the morning or coming back late is a bit of an issue. Dispite the sound passing SVA it’s a tad disruptive....
Adjusting valve clearances and a new rocker gasket
Fix the jump leads - no continuity = useless jump leads. The copper was crimped and cut straight through at the factory. Trimmed and now soldered - much better. Inside...
Service
Service time! New oil - fully synthetic ester Managed to avoid spilling anything on the ground for a change! Being able to take the side off the engine bay really...
New 6 speed gearbox
The current clutch slave is about to pop, the mechanism for moving the clutch in and out appear to be overly stressing the hydraulic components. As I’ll need to take...
New Optima yellow top battery fitted
Bonnet (hood!) off in Roadkill tradition, but to change the battery, not overheating ;) The old bosch has taken too much abuse over the years and doesn't hold it's charge...
