a few timing questions

[jasonleee09]

This is my first 4g63 and I'm doing the timing/replacing the valves. What are good places to get parts that isn't over priced. Also on my vr4 I had I had cam lockers does anyone make them for this engine?

Paid almost nothing for the car, knew it had bad timing. Well once I got to taking it apart I noticed the guy put the manual tensioner on backwards so yea was never tensioned correctly. Got the head off and he bent all intake valves and hair line cracked the guides. But some how managed to not damage the pistons or the exhaust valve side . Got my head in the machine shop and doing the balance shaft eliminator, waiting on the parts for that from dsm graveyard.

Ok cool, you have the guides being replaced and the seats cut.

Hope the machine shop you picked understands DSM heads.

Let us know how getting your parts from DSM graveyard goes.

Some read for you on cylinder heads.

you sure your hydraulic tensioner is keeping constant pressure? Did you put enough pressure to the manual tensioner? Also using the correct timing tools makes a hell of a difference, i just ordered mine alone with some cam lockers .

What the hell is a "cam locker" on a 420a?

Well first of all thank you for the info. I used the machine shop a few years back and they did great work so I'm hoping its all good . As for DSM graveyard its been a week and still not shipped...Just can't wait to get this thing running. Already got the turbo harness and computer for my next year project. Going to buy another engine and build it from the block up...benefits of being divorced no more nagging wife .

Well its not a 420a so reading the post would be appreciated. For the 4g63 its this STM: AMS 4G63 CAM GEAR ALIGNMENT TOOL | EVO VIII-IX | 90-99 DSM locks the cams in place for when you do your timing.

Just found VFAQ the other day and love it. Timing on this motor seems a heck of alot easier than my VR4 was...never again

A 3000GT VR4 I assume? Yeah those are a pita all the way around.

Must have been the DOHC 6G72 using just one long belt to run over all of them cam sprockets and water pump.

Yet, with bulldog clips to hold the belt in place over the four cam sprockets, one think it wouldn't be too much different than doing a 4G63 with just two cam sprockets, being still with just one adjuster.. True, sideways motors are alway a PITA when doing belts and similar when still in the vehicle.
