1st Gen Lunchtable Thread - General Discussion

I think all except the 3mz. Would probably hit the exhaust manifold but maybe not.

 

Every 50k you should at least check them, they tighten up fast

 

I had mine done in 2008 when I got the new head. Still runs strong just does not like the below freezing temps in the morning. so I start the truck 10 minutes before I leave for work.

 

My brother-in-laws car really throws them off. I have to tell them its an 07 optima instead of an 06 since 2006 was a mid year new generation type thing. If I say 06 they wanna know the vin, how many wheel studs etc.

 

My 3rz just passed 100k. Never had this done.

 

I'd get em checked. Was a bummer to launch $2500 on a head for one. Mine was at 172k with one previous relash

 

I think I've maybe did 20,000 miles on my 2rz since 2008.

 

Fram gang. Did my first oil change with the new cylinder head thousand miles ago and had to get the tough guard lol

 

After paying 3k for my hg and head, the slug will be getting em checked every 30k religiously

 

Aight. Its got to go to a shop here soon anywho.

 

Is 30k too ambitious then? They clearanced mine upon putting em in the new head from what they said

 

The Toyota FSM says it should be checked every 50k and that adjustment isn't always necessary, same thing is said about the 5vz too. Difference is the 5VZ rarely shows a change the 2/3RZ heads seem to be soft, the seats wear hard and they need reshimming.

 

Well plugs need to be done every 35k if you buy the oem coppers, so its a good time to check the valves too.

 

I went with ngk iridiums so I didn't have to gap them. Guess I'll be looking at everything around 175k ish since I got it all done at 125k

 

You wouldnt have to gap copper plugs either. This isnt 1962 anymore.

 

It's more so checking them and preventive maintenance with adjustments as needed then? IDK where I saw 30 k lol

 

Yup, get em checked, which ever ones are out of spec you just put in the right shim to get it back in spec. It's a pain, but once you buy the tools and learn how it isn't too bad. Nothing besides the valve cover really has to be removed.

 

Very good info, thank you
