Evening

I know I’m new to the forum and is a bit cheeky to ask but wondered if you could give me some advice on the cossie valve timing. I did put a thread up but not sure why it didn’t post up. Basically, I’ve had the cossie a while now, and the head gasket went, so I took the head off to find out that the pistons had damage marks from the valves from a previous battle wound, so decided to take the engine out strip the whole thing down and rebuild it. so replaced the pistons, rods etc had the block checked and decked and had the WRC long stud conversion not the arp bolt in type stud kit but the conversion where the block is machined anyway engine is now back in the car and just getting the old girl timed up, I don’t have the standard cam pulleys as using turbosport vernier pulleys. So, I have a tool that my dad made he’s a retired mechanical and electro engineer and has also been helping with the above. Here is a pic of the items I’m using to find true tdc and I’m also going to be using to setup the cam angle for timing.



You can see the tool for finding TDC thats been made using a old cossie spark plug, also made a piston stop tool with the same idea but with a thread so you can adjust the point and lock it anyway, so i fitted the angle disc onto the crank and used the gauge to find true tdc, heres a couple of pics, i did tweak it enough so the needle was bang on zero on the gauge and angle disc but just used these pics for showing you my setup so far




So im happy number one is in at true TDC now. My next step is i want to get the cams in the correct positions. Im going to use the tools from the first pic with the clamps and the welding wire and the gauges to adjust the angles needed for the exhaust and inlet



So will have it all rigged up so that the wire is touching the face of the bucket, ignore the mess as will all be cleaned up.

But what I’m not too sure about is actually how to adjust the inlet cam then the exhaust cam while number one is in TDC. If anyone could give some advice as would really appreciate it or if your local and fancy popping round more than happy to pay for your time if you can show me. the car is running standard cam shafts and made sure there the correct way round as I know they can be placed either way, but the cam with the groove cut out is on the inlet

Many Thanks
Sorry for the long-winded thread and crappy pics doesn’t help you much

have you still got the original camshaft pulleys.if so put them back on its alot easier you wont need the dti or the rest of it. you would be able to use the original timming marks
