Hi guys, I am currently rebuilding my 1HDT motor and my camshaft had a bad wear (water or bad lubrication maybe), I decided to buy a used camshaft and then found that it had a light wear as well:
My mechanic said its better to not take the risk.
So I decided to get my money back and start looking again for another 1HDT camshaft.
I was not able to find another one, and the new one costs $1600 here in Costa Rica.
After digging around, I found a 1HZ camshaft like new, so I took mine (1HDT) and measured both.
*Keep in mind that the 1HDT and 1HZ camshafts have different parts numbers (13501-17020 & 13501-17010)*
Surprisingly the 1HZ camshaft is 1mm bigger than the 1HDT (why? dont know! I suspect because Toyota needed to supply power from somewhere if there is no Turbo), I used a digital caliper and measured the Base circle and lobe lift.
My mechanic said that this is not a problem at all if the head (valves and everything) is calibrated with it and actually might gain some power.
This is something I wanted to read somewhere on the Internet, but it does not exist! So here is is for everyone else, hope it helps you guys!
