Re: VHPD Engine inspection

Went into the garage today planning to clamp the liners into to block so I could rotate the engine. The normal method appears to be to use the stretch bolts that hold the head in place with some big washes and a bit of copper tube the height of the head to hold the liners still. I found it did not h...

Great news. Will check the calendar and hope to join you.
Sign up for the Ashbourne group and can get me as a leader. It’s always a good ride out.

Re: Exhaust restrictions

Generally, exhausts make no power difference, just feel good (or bad) noise. I always like the Chris Tullett, Eliseparts, exhaust I had on my S2. It was nice and quiet and repackable.

Re: VHPD Engine inspection

The valves do not leak. I filled them with meths and nothing trickled past them. I plan to remove them as the exhaust ports are full of soot so I can give the head a good clean. It’s coming to decision time on what to do. I’ll most likely just loosely reassemble the engine as it’s intended to be a s...

Re: VHPD Engine inspection

Checked the liner heights and they are ok. I just put a steel rule across the liners and measured the gap underneath with a feeler gauge. https://i.imgur.com/Rr1JgOl.jpg So all is well but I do have some marks on the bores which Dave Andrews tells me should come out with very fine wet and dry. I’m g...

Re: VHPD Engine inspection

A little more progress. I have removed the cam ladder as I know all of the valves need different shims. I want to check if the valves are sealing soon. My plan (once the head is off) if to inject some meths into each port and see if it trickles through. No idea if that's a good sealing test but it's...

Re: VHPD Engine inspection

Some progress. The flywheel bolts arrived from EliseParts. These are just cheapo ones but perfect for the job. Using two bolts was able to jam the crank on my engine stand using a screwdriver. The bolts have a much finer pitch than normal bolts, so don't try odd ones you have lying around. The pulle...

Re: VHPD Engine inspection

I’ve been a bit busy. Ordered some flywheel bolts so I can jam the crank. Progress soon, I hope.

Re: VHPD Engine inspection

I did not really appreciate point 1! I do now. I'll have the crank clamped before the head comes off.

Re: VHPD Engine inspection

Useful advice time. After a bit of searching and talking with a Gavin at Unit 4 today I have learnt that once the head is off, if you try to turn the crank over you will lift the liners and they will have to be reseated and sealed. Gavin also advised that he has never seen a Lotus with a damaged bot...
