Camshafts, bearings and intake

Posted onLeave a comment

Here are the camshafts. Coatings for more slippery 🙂

Sadly, at the moment they’re the only engine bits I have. Rest of the stuff is at Martelius’

The bearings thing.

I spoke with a friend about conrods in general and also about symmetrical conrods, when I realized what the “always turn the engine to normal rotation direction” means. I’ve thought it had something to do with piston rings but oh boy was I wrong. It’s about bearings.

See the little notch there? The bearings should have a tang that goes into that notch. If the engine is turned “backwards”, the bearings could dislocate and jump off the notch, maybe resulting spun bearings.

Fuck I’m an idiot! I havent ever realized this before 😀

Second peek to the intake! Still much to do.

Coilpack, camshafts and one corroded valve

Here is the corroded exhaust camshaft getting polished

…and testfitting it

Brand new intake camshaft

Quick test with the coil on plug. This is one of those long Lexus COPs that are used in RX300. It fits but some fabrication is needed.

…and last, one of the three corroded valves. One might think that the corrosion would be on the exhaust valves, but for some reason it only affected intake valves.

Valve covers are off – camshafts look fairly good. MRP turbo manifold testing.

There was a reason behind this pic but I’ve forgotten it

Trying to figure out if I have stock camshafts

That 212 in the casting made me wonder – stock camshafts are 232° if I remember correctly, but then again, it could be 272 (TRD camshafts). Measuring the cam lobe finally told me that I was dealing with stock shafts. Woo-hoo.
