3RZ-FE replace timing components during head gasket change?

Hey all,

Replacing the head gasket on my 1998 2.7L tacoma (3RZ-FE). Taking the opportunity to do some other work while I'm in there. My timing chain/tensioner/guides look fine as far as I can tell - and from what I understand these parts are meant to be "life-time".

I don't want to go through the process of removing the timing cover to replace as I work pretty slowly. However, if its recommended to replace these parts (I'm at 270k) then I'll do it. Does anybody have experience here they could share?

Thanks.

 

Tough call the head is off !

Me I would do the timing chain while every thing is all apart.

My luck runs I would be pulling it apart in a month or 2 if not sooner.

Like all decisions it will always be your call.

 

Like said previously, it's just your call on the risk/reward ratio.

Risk: Have to take it all apart again soon.

Reward: Save a few hundred dollars (spitball guess #) in timing chain components parts cost, and a couple hours labor right now.

Good luck either way!

 

Yeah I ended up spending 600 bucks at the machine shop for a valve rebuild so at this point I'm feeling pretty committed and will be replacing timing components (plus oil pump o-rings/seal while I'm at it)... Hope to have her back on the road soon

 

I think you'll find if oil was changed regularly, those components will be just like brandnew...

maybe the tensioner may be a little sticky.......

so its a flip of a coin.....


If it was me I'd replace all that stuff....with the exception of the balance shaft chain....
and even that, I'd get a new tensioner.


One thing you may have to consider is getting a seal saver for the front oil seal...
might want to inspect that shaft carefully and pester the mechanic......
270K mi is a lot of miles on that shaft and seals.

 

I (work slow), never miss an opportunity “while I’m in there”.
