So I just posted a forum in the electronics forums about the sub amp, but basically, my girlfriend and I are sharing her new 1996 SC300. I have been racing for a few years now (It is a domestic, but sh!) so my mechanical inclination is pretty great and I feel absolutely comfortable doing just about anything. But I noticed that car has a few quirks I want/need to fix. We got the car in TX (where I live) and drove it for a few weeks to work out issues. I seafoamed EVERYTHING (crankcase/oil, intake/internals, and gas) and gave it a nice change of oil with RP 5W-30 (I think). We drove it 1100 miles to Denver, CO with NO (like, none) issues. Now that I am here, it has 124k, and still NO CEL or mechanical issues. To save people from reading my life story, here are the issues the car has with 124k miles: 1. The car makes a clunking/popping noise from the front suspension SOMEWHERE. I cannot replicate the issue without driving the car over a bump or turning the steering ALL the way to the left or right in reverse. Any idea what that could be? I don't want to throw money at it, but I was probably going to order a poly bushing kit and just replace everything I can on both sides. 2. There is a mild oil leak at the back of the valve cover. It keeps the back of the head slightly wet and gunky. The oil level does NOT move. At all. I feel as if this was a pre-existing condition and just won't ever be 'dry'. When I changed the plugs, I tightened the valve cover bolts and noticed they were relatively loose. I still want to change the gaskets. Would this more than likely solve the issue? 3. The timing belt... Looked pretty new when I had the cover off, but I don't have the resources to change it right now. Are these motors intrusive? (IE: If the belt breaks, is it going to chew the valves up?) I really would like to change it, and I have a new Gates belt, but I can NOT make time right now being at school... So that is all my questions! I really appreciate any advice. If y'all have any questions about the car, I would be more than happy to answer! Thanks, Kyle

Hello! My name is Kyle and I have been poking around on the forum for a while getting help as I am new to 2JZs and Lexus in general (I have a Trans Am, the Lexus was the car I helped my girlfriend get, don't hate me, I love muscle ;) ) but I have a great mechanical inclination and have installed radios in nearly everything. But I just wanted some advice on the stock sub amp in these cars. So, when she got the car, the sub worked and I was wildly impressed with how good a stock system can sounded. I installed a Pioneer P400DVD touchscreen in it, bypassed the stock REGULAR amp per a guide on this forum. Sub worked AWESOME for a week, then just stopped making noise. One speaker had already stopped working in the back, so I replaced everything back there. I fabbed up a way to mount a run of the mill Kicker 10" in the hole, and replaced the other two speakers with Alpines. ANYWHO, the sub still doesn't work, so I narrowed it down to the sub amp. Is there a common, easy to fix, thing that happens to these? (IE: Just replace a transistor) Are they hard/expensive to find? Or should I just bypass and run just a cheap single channel? Again, it is my girlfriends car and doesn't have to a rolling concert, but I like bass and I drive it a lot. Haha, so just input on getting that sub working again would be greatly appreciated. Thanks, Kyle! P.S.: Awesome forum, can't wait to to stretch my arms into the 2JZ world ;)
