Got the intake off the car to do a Fast 92 swap. What else should I do for preventative maintenance while I'm this far into the motor? Oil pressure sender?

Car is an 02 Z.

Thanks,

Oil pressure sensor relocation

STL Mike

Any details or build thread on the relocation? Assuming this is b/c it's difficult to reach with the intake installed?

Get a paint brush and good vacuum cleaner and make sure you get all the loose sand and stuff before pulling it. This should help prevent any going into the intake ports. You won't believe how much is laying around.

There was a TSB on the knock sensors where a dam of RTV is used to prevent them from getting wet. Might want to search and see if it applies. Check the vacuum lines behind the intake. If still running the original AIR setup, might want to either clean or replace the passenger side valve which sits behind the driver's side head but requires intake removal for access.

some doc's on my relocation,

This is from the TSB for a 2002. Steps 1-5 were replacing the sensor which you aren't doing. For some reason they don't run the RTV all the way around the seal for the sensor and they don't do the front sensor. There is no TSB for the 2003 or 2004 and the repair procedures don't mention using RTV so I assume they must have improved the the seal to keep water out.

discard the coolant line running though the throttle body, and maybe redo the steam lines, I did and have no more issues with air trapped in the system.

For sure

find Bill Curlee's system for the steam lines way cheaper than what I did. (he used a front steam line on the rear)

STL Mike

Thanks, you guys are the goods.

How would I ever know I had steam problems? Is this boiling coolant at the high point of the system?

Pounder

there are coolant lines running under the intake, some intakes don't allow enough room under them so you need to relocate them. Some just flatten them out for clearance, but I feel using the kit I mentioned allows the air not to be trapped in the heads. Th is page shows Bill Curlee's method,

What does a steam problem look like on a street car?

I pulled the manifold and found grass in the lifter Valley. Is this common being a bottom feeder?

Also, any ideas on what injector this is? 36lbers? Wondering if now would be a good time to upgrade to a Ford 42lber green top.

STL Mike

Also, I noticed when I pulled these injectors out of the fuel rail, there is an additional o-ring in the fuel rail in between the injector and rail. Is this normal?

STL Mike

O ring in the injector rail the norm?

neutron82

yes there are 2 o-rings on each injector, one at the top and one at the bottom

STL Mike

No no, the injector has 2 o-rings on itself. There's also an o-ring up inside the fuel rail that the injector top rests against. I thought that was weird.
