Right, I've made a start. I bolted this bit to this other bit.
Seriously though - inside the heart of the beast
Now, I decided that I would check out the cam when I was in here, just to check that it was timed correctly. Apparently the RP4 camshaft should have full lift at 112 degrees. I have heard that the RP4 is specifically for autos and heavier vehicles
. I have looked at the Viper Cyclone which was developed for the 3.9 Hotwire engine, which is very close to what I have, but have also heard that the RP4 and the Cyclone are basically very similar cams from different manufacturers, so what do you believe? It would really be the best time now to change it if I wanted to
Anyhoo, I made one of these a while ago and found the timings marks were 8 degrees out, so I adjusted it as much as I could but it still reads 1 degree out.
Just ensure that number one cylinder is nowhere near TDC and insert this piston stop then turn the engine by hand until it stops - 17 degrees ATDC
Then turn it the other way until it stops - 15 degrees BTDC
So I took the pointer off, cleaned it and the area where it sat, filed a bit off and hit it with a hammer, now it sits exactly on TDC when at TDC, so we know it's accurate.
Made this and stuck it to the pulley
I'll sort out my dial gauge and check the timing shortly.
When I was in the engine, I had a look at the huge wadge of shims under the rocker pillars, which I have never been happy about. (I bought the car with engine fitted - badly)
But this was a bit of a shock, this one had turned round and the bolt was actually loose.
I tightened it up but the shim turned with the bolt? So, off it came and shock horror, the thread had stripped in the head
Do I take the head off and take it to a machine shop for a helicoil, or do I do it myself, then take it to the machine shop for a helicoil and sort out my bodged attempt?
Also, this lovely bracket doesn't fit the P6 front end (Not even close), and three of nuts supplied with the kit are the wrong size.
All part of the fun when owning a classic car I suppose.
