Timing chain tensioners

[Sc0-]

Possible to change the chain and guides without pulling the head?

I have noise coming from that area and the only thing i can think of are the guides coming apart. Lots of nose when cold, a little noise when fully warm. Not belt, power steering pump, water pump, or accessory/pulley related... I need to reseal my oil pump, change out my front main seal, and swap alternator pulleys when it's apart so just wondering if it's a few more bolts or if the head has to be removed.

I think you can remove timing cover, but I am not 100% sure I did all that , but timing chain .

Quoting from an older thread here: 1fz-fe Head Removal

The oil pans (plural) must come off, and you'll need a lift, or a combination of jacks to get the pan "out" once it is "off". Then the air intake, throttle body, plug wires, distributor, valve cover, 2 front head bolts (these are also timing cover bolts), AC compressor, compressor mount, water pump, alternator and bracket, idler pulley, thermostat housing, thermostat, (pulling radiator is optional, but I did for more room and to protect the top tank), lower radiator hoses and steel pipe, steel pipe mount, vertical water bypass pipe, horizontal water bypass pipe, stabilizer bar under back of engine, USDS stabilizer bracket.

Unless you have a leak, broken chain or slipper, or just want to spend an additional 30 hours working on it, I would leave it alone.

But yes. You can do it without removing the head.

Probably not the chain but piston slap, pull the valve cover and look at the guides
