    Does anyone have any experience with the cams lock tools not wanting to lock together well? They both sit flush on the head with cams at tdc. The problem is the little hook at the top doesnít really want to grab the other side. ? I also cheaped out and bought a eBay timing kit ...

    eBay blocks are garbage. I had the same problem awhile back. Had to borrow a set from a local member

    Thanks for the reply and your right Illjust start with some quality tools because thatís most likely my issue.

    Iím also scared after reading through a pelican article that my oil pressure relief valve was still installed. I never checked and head is already on with cut ring, manifold ect. Is there a way to check this without removing head?

    The machine shop has always either left it or put it back. Hopefully that is the case for you.

    First time using them and After messing around with them for a bit I got it to latch but they did take a little work. I wouldn’t recommend them to anyone. The cams do appear to be timed correctly tho.

    Their a good machine shop and gave me a bag of anything removed already. Ill hope for the best then ����

    While waitng on new vanos studs I began to mock up my piping. Its not tightened down yet and needs some new clamps. The coupler off the 90 on the turbo is really close to the block and manifold. I clocked the turbo best I could was thinking about heat wrapping it with something?

    You will cook the coupler if it is too close. Wrapping it with fiberglass wrap could help.

    I used ebay blocks align the cams install one block then swing arm to fit other side adjust cam according. tighten. then recheck cams after arm has been connected between blocks. timing is perfect. 44$

    Small progress

    I went to install the vanos and related parts today but was sent the wrong bolts. I ordered all new hardware from pelican parts but didnít receive what I needed. Not a big deal just have to wait. In the mean time I set the timing on gears with new chain. Then placed everything where it needs to go. Hopefully this weekend will torque it all and be good to go.


    Next step is to figure out my wiring harness. When I took the car apart I didnít label anything like a dummy.

    I too have Ebay ( or Amazon ?) blocks. My took a bit of filing to get them to sit right. I got them sitting right before I removed anything, when I knew the cams were locked tdc (flywheel lock pin in, and chain and everything installed). They work fine now though.

    I had the same problem on my setup, coupler was pretty close to the manifold. I used aluminized fiberglass heat insulation. I have about 1.2k (so not that much) now with the new setup and no problems yet.

    Glad to hear itís holding up. I figured a lot of guys run the SPA manifold and would have delt with this. I went ahead and took your idea , thanks

    I'm running a reinforced silicone coupler with heat wrap similar to below. After five years of boosting, so far so good.

    best way to check wiring harness

    I didn’t label anything when I took my motor apart and this is a new motor.This weekend I started to wire up my harness. Most of the wires seemed to lay and go where they wanted to. I’ve never done this before but was wondering the best way to make sure I got it right? I was thinking about getting a pin out out from the main harness plug and testing each sensor plug for continuity? So then I just need to order a new crank sensor and do my fuel lines and the manifold can go on.

    Where are you posting parts for sale?
