Anyone got photos of oil pans that were modified to clear IFS on 86-99 trucks/4runners? ChilKat isn't doing them any more... I've got one photo, but would like a few others for some eye-ball initial fabrication:Can they tell you how much differance there is between the ones they sell and the ones you need (solid axle vs independant)?Did you call and talk to them?
3RZ - DO IT
Gak.. having the T100 pan modified for IFS trucks - going rate is $600 after buying a pan... Someone let me know if there is a better option... Was told if I DIY'it that I need to weld it with it on the block to avoid distortion.
I understand that it's likely to warp with too much heat. I've got a motor out and on the stand, so welding it on-stand isn't a problem, just cover the internals so no slag gets on a cylinder wall.The 2rz I have came with a pan. I also ordered the T100 pan for the rear-sump swap.Sure, it's more work.. The question is how much more work - if there is a ton of trial-error fitting, it may be worth the $600 to have it done... The shape is not simple (see the pan above) - they're not square cuts... Just surprised there isn't a drop-in pan for this.. Might be simpler to modify LCE's 5" square pan, just pulling it up around the diff - less reduction in capacity and easier to weld on with square cuts.
Finally figured out the problem in H8pvmnts old 3RZ. Between my work and the shops, we tried alot of things. The shop is a mostly toyota shop and the mechanic has done over 10 3.4 swaps and 4 3rz swaps. He works on these every day, and we still had to just keep trying things, because even his new Snap on scanner didn't really help. In the end, after checking wiring, changing O2 sensors, TPS, CPS checking valves, vacum lines, ecu, etc....IT WAS THE FUEL INJECTORS. The strange thing was that they were all apparently bad. All the plugs were fouled out. We changed the whole fuel rail, regulator, and injectors together from a parts engine. The computer was trying to richen things up, and it smelled rich because of exhuast leaks and strange injector behavior, but it was just running out of fuel. When we misted fuel into the intake while reving it, it reved up quickly and much better. So we tried the injectors. Even pinching off the return line didn't fix it so we figured it wasn't fuel pressure to the rail. Anyways, it still surges a little here and there, but it still has exaust leaks and has an older reman MAF. Its obvious the main problem is fixed though. Hope this helps some others. Heading to the oregon dunes with this and a rzr 900 next weekend... Thanks everyone.
Have you checoed the injectors yet? Put a noid light on em. Maybe better yet. Pull em out n have em rebuilt or at least checked.. maybe one of them has failed and is dumping fuel? Maybe even the ecm or ecu...
The only line I worry about is my fuel line. It runs up the passanger side and its too close to the header for comfort. Still trying to decide if I wanna move the hard line or make a shield. What did you all do?
