Checking cam timing & upgrading to hydraulic tensioner part Qs
 

Okay
I'm in the process of ordering the metric dial gauge & z block. We are going to check cam timing (have our reasons for this).

While we are at it, we will upgrade to carrera tensioners. Last year, I bought most of the components from a pp forum member. I need the oil lines, new timing cover gaskets, and what else? already have the covers and tensioners assemblies themselves.

What other gaskets and hardware will I need to replace while I am at? I already have new valve cover gaskets and hardware set aside.

TIA

I bought the tensioner upgrade kit from PP and installed it last year. The oil sending unit on my 72 is located close to the oil thermostat rather than in-line with the oil lines. If you don't have the unit in-line with your right side oil line, you will need the longer right hose (PP part number PEL-CLIN-KTN fit mine). The stock left side hose from the kit fit fine.

The left side cover that came in my kit was for newer models with air pumps. If you have the newer model covers, you will also need two longer M6 studs for the air pump bracket mounts. Since you don't have an air pump, the current studs will be too short. I just took the left cover and old studs to my LPS and matched up longer studs with the correct threads. When you install the cover, be sure to use a steel washer under the crush washer/nut as the 2 bracket mount holes in the cover are for M8 studs. This will give the crush washer something to press against rather than be cut by the M8 sized hole in the cover.

Then, there are those oil line supports. I'm pretty sure those little solid pipes would eventually fail due to vibration/oscillation were they not supported. More experienced folks may chime in regarding those supports.

Also the new cam line restrictors are recommended when you switch to those tensioners. Some don't like them but I think the general consensus is that they do benefit especially when using pressure fed tensioners. Do a search and decide for yourself! The part # is PEL-CAMRSTN.

Yeah there is a big discussion on those... I put them in my rebuild, but read for yourself:

Michael - thanks for the thread post. I hadn't read that one

For me that says it all!
