I have an old hilux with a 3L naturally aspirated in it.
I had to change the injector pump and injectors recently.
I put everything back together with the timing marks on the pulleys lined up. Turned it over by hand to make sure the marks still matched and it all was sweet.
I went on a trip recently and struggled up the hills.
I assumed the altitude was not helping but I am still missing power at sea level.
I popped the oil cap off and there is considerable air blowing back out.
It's the same at the air filter too.
First thought was excessive wear in the engine but now I'm wondering if the timing belt could have slipped a tooth on the cam pulley?
I was hoping to not have to strip it back but I will if I need to.
Any suggestions or thoughts as to the cause of this?
