Timing Chain Inspection and Replacement

[Tynan918]

Is the fan, water pump, and harmonic balancer the only things I remove to get to the timing chain cover ?

my bet is he doesn't have that timing light.

565bbchevy Yea I don't have that kind of timing light... 🤦🏾‍♂

That being said, I would buy a tach from the parts store, carefully un-package it, connect it under hood making sure it's correct for reading the V8 configuration & see what it says vs the one tucked in the dash. Keep things from getting dirty & return it within a day or two in new condition to get your money back.
OR..... Keep in in the tool box for easy future monitoring on any vehicle you need it for. I keep a small <3" tach in my 'tuning' tool box just for this purpose. I think the little tach was <$40. Good tool to have for flexible use on multiple vehicles.

Not a bad idea, I'll look into that !!

I would imagine that your mechanic relatives either have one or something else that will read RPM that will sit in the engine compartment, maybe they just use a spare tach to get a reading.
This one is similar to what I have.

Grandpa was the major mechanic, did mechanics on tanks and other military vehicles in Vietnam, he worked on Mopar vehicles. He's 76 tomorrow... I don't believe he has a timing light...did timing jobs with him before without timing light and never used a timing light with him.

I have two uncles who works on cars...one actually has strong mechanical experience and I believe he has a timing light like that...maybe, but he distances himself from the family. The other uncle does mechanics, but not like the other uncle. He's working on his Challenger R/T heads and other engine work right now at my grandparents, but they don't have this timing gun..

All I have is the dial type timing light.

Also, removing the dash bezel to get to this tach to inspect it, doesn't seem too hard to do...

It's not too hard to access it for removal. It is another task to do which adds to your list.

Tach adjustment was set for a 4 cylinder engine....

So what does it read at idle now?
