A few weeks back I decided to replace motor mounts, trans mount and cross member mounts (from MN12 Performance). I lowered the sub frame, as this was the best way to do it. While I had the car up on stands, I replaced trans fluid with Macron V after draining both the trans and converter. I then replaced engine oil and filter. After reassembling the motor mounts and bolting them to the engine, I raised the sub frame up to align holes in mounts to sub frame and installed the long bolts. Raised sub frame to mate up with body, and bolted up.
Saw that I needed an "arm to frame" bushing on driver's side, so replaced the whole lower control arm, since the price of the bushing was approached that of the whole arm assembly.
When the sub frame was down, it stressed the high-pressure lign on the power steering pump, and resulted in a leak from all the o-rings on the EVO assembly. Got new o-rings for swivel fitting (thin 1in and thin 7/8in), and the two fat o-rings that seal fitting to psp. No more leak.
The trans cross member bushings from MN12 were poly, and I drilled out old rubber bushings and dremeled remainder out. Used high grade bolt and socket over bolt to drive the bushings into the shells of the old bushings, using a pair of Chan' locks as a spacer between cross member and body of car. Used an impact to drive the bushing through. The last 1/8in requires a considerable amount of force to "pop" it all the way in. I was worried the nut inside the body would give out, but neither one did. It took close to 150lbs of torque to get the poly bushing in right (air pressure setting on cheap impact gun). I was glad I was able to do it all with the cross member on the car.
Had the top IC tube off so I could get at the EVO Assembly on the power steering pump to replace the o-rings, so I decided to un-bolt the lower IC tube and redo the gaskets on them both. Ended up using "yellow colored case" Teflon tape and some multipurpose adhesive in a spray can to keep the tape in place on the male fittings. I posted how I went about installing the tubes in another post, so if you want the details, just do a search "discipled1" to find it.
Replace the rubber hoses that are inline with the trans cooler metal lines with high pressure hose and fuel injection line clamps.
Replaced brake power booster.
Checked toe on front and back wheels with tape measure and adjusted front toe out problem. Have to wait for full 4 wheel alignment though. I have no idea what caster is, but camber looks close.
The engine runs really smooth now and has lots more power. There must have been a leak in the IC tubes that was causing poor idle and loss of power. Now, boost generates faster and it stays longer, but still hitting the same numbers on boots gauge (about 10lbs at WOT).
The car feels much more stable in the front end as well with the new lower control arm. Steers straight and with the new motor mounts and trans mount, the car feels more solid. The trans fluid refill with Macron V has made the trans work soooo much better. Must have had Macron III in there when I bought it?
After test driving the car, I was very happy with the improvements in handling, feel and performance.
I did however get a CIL and a DTC of 332 after WOT. I'll check the EGR stuff tomorrow.
