I too will offer the services of our shop (actual buisness oriented shop). If you ever come down here Coomer... I'll hook you up... ;]
Anyways... if the car drives, then most of the wires (to the ECU) should be correct... or at least the important stuff. The tapping in the head is pretty typical for 4AGs and a simple valve adjustment may be able to cure it. At least 2 of my various 4AGs I've worked on tapped at idle... and were cured with valve adjustments... I'll guess it's all in all the same with the Silvertop. As for the VVT solenoids... I'll look around for my old diagrams and see if I can dig something up. Honestly Coomer... not just so you'd keep the Celica... but if I were you, and have put up that much time, commitment and money into a project... I'd be far too stubborn to give up. I went through 2 13B rotaries and an entire Celica before getting rid of my old RX7... and finally settling down for a bit with my current Celica... and now, I've already gone through 2 4AGEs and 2 Corolla GT-S... still not satisfied... ;] keep at it.

defective ECU, hah, im pretty sure if one part doesnt work, then the whole thing wont work VVT only engages when the speed, oil pressure and RPM's are at the right place right? are you positive that those sensors are all in working order? if you can, get a cheap beter car and pull the engine harness so that you can work on it inside and on a table, thats what my friend and i did with his 240z we checked every single connection in the entire harness do you have any wiring diagrams that i could maybe look at and possibly give suggestions on what to check? -------------------- 1994 Celica GT4 WRC Edition

Thanks!  The car drives perfectly, except VVT just isn't working, so yes, I think most of the wires are correct. It's probably an issue with my speed sensor or TPS that's causing VVT to not work. I'll have to look into how to adjust the valves to get rid of the noise as well.
Yeah, the ECU most likely isn't defective. My mechanic insists that my ECU is bad, yet he doesn't know much about Toyotas, and I'm pretty confident that he screwed up my wiring somewhere. VVT engages based more on RPM and speed sensor input on my pre-'93 ECU...I've checked the speed sensor wire, and it seems to be fine. My RPM wire also seems to work fine, as my tach functions perfectly. And I'm not sure on oil pressure...I don't think it affects whether or not VVT comes on. I know that the engine has to be fully warmed up for VVT to turn on though, except for the very short time interval when the engine is starting. -------------------- New Toyota project coming soon...

Augh! More problems!
 A couple days ago I turned on my high-beams and the indicator light in the cluster slowly lit up to maybe 30% of its normal brightness, and I noticed that my brights weren't as bright. Once I stopped, my passenger side high-beam looked like it was on at maybe 20% power, so I figured I had a burnt out bulb causing some sort of a short. Well tonight I replaced the bulb with a brand new one, and it lights up exactly the same. It's just problem after problem after problem with this car. I was thinking of selling it and buying a GT and doing a swap, but I'm not so sure that I want to go back to a Toyota again...my 7A-FE and C-52 both died around 100,000 miles, my stock hydraulic system is failing, my car has had(and still does have) weird electrical problems, etc.

Man coom I really do sympathize here. My old S10 truck had so many problems, electircal was a mess, the engine was leaking oil from too many places to even begin to list, the suspension was a big mess, it got broken into one night and someone stoll my stereo and also ripped the entire dash apart (there was no way of fixing it unless I built an entire one from scratch.....) I finally gave up on it and donated it to the kidney foundation lol. If I were you I would keep on truckin with it as funny as that might sound, with all of that time and money that you put into it....man. You might want to take the car to a professional who can diagnose electrical problems, if they find out that it is wrong take it to your mechanic and threaten to sue if it is not fixed. That guy just screwed you from the get go with that car. It sounds like you have an alternator problem since your lights are not working correctly, check to see if it is working properly, you might have fried it with all of your stereo equipment. Hope that everything works out for you.

Yeah this is a really good idea. Its better to spend like 100$ to ind out the problem then to keep being constantly frustrated. Also, Have you asked your local toyota dealer mechanics for some ideas? I know the Dealership by me answers any questions that I have. BTW GET A NEW MECHANIC |

OMG!
My mechanic is straight-up retarded! I decided to pull off my fuse box cover last night and see if I'd blown any fuses. What I found in place of a fuse for the right-hand headlight was a melted wire connecting the two metal connectors together! Apparently when my mechanic was burning up fuses trying to get my VVT working, he took a fuse from that place just so that the car would run again, because we were out of fuses. I just can't even believe that he used a thin wire to replace a fifteen amp fuse. I'm lucky that it only melted, and didn't light my car on fire. On the positive side, replacing the melted wire with a fuse fixed my problem.  Jeremy1210, my Toyota dealer isn't very helpful when it comes to asking the techs questions...they know though so they let me borrow shop manuals and stuff. Digndoug, it sure is tempting. I was at the Toyota dealer today and they got a silver E36 M3 on 18s from a trade-in, and they let me test drive it. Man, that thing was fun...lots of power, an awesome interior, and pretty nice looks...too bad I couldn't afford it. -------------------- New Toyota project coming soon...

Coom, so you're hitting VVT now?

Coomer have you checked the harness clips.. .. the one of the connectors might be pushed back.. so the ecu or the engine might not be getting the signal ..

Yep, I checked those, and I know that the VVT wire is connected, because it will give me ground when the car's ignition is off. And yeah, I'm still not hitting VVT. Today I was going to hook up a push button switch to the wire and to a ground source, and then manually enable VVT while driving by pushing the button, just to see what it'd be like. However, after looking at five stores all around town, I couldn't find the switch that I need.

Yeah, it would be nice, but none of my friends have enough tools to do this. And my mechanic wouldn't do it, because he insists that it's a bad ECU.  However, on the way home last night, I had a good idea. It's possible that I'm not hitting WOT, and that may be causing the VVT to never turn on. The throttle cable that was originally used for the swap quickly developed some slack, so the pedal would move about 1.5-2" almost completely freely without affecting the throttle position. I found a throttle cable off of a wrecked Paseo shortly after, and installed that into the car...without the slack, the car felt much better to drive, and the pedal didn't make as much noise. Now the Paseo throttle cable has developed lots of slack in it as well, and it's possible that I may not be hitting VVT because I'm not hitting WOT. I hope this is the problem...I'll probably get another throttle cable off of something next weekend and see if it fixes my problem.

Woo Hoo! I just found out that the clicking I'm getting at idle is normal, and non-detrimental to the engine.
Thanks Sphinx! Apparently it's the loss of damping oil inside the VVT mechanism that's causing the noise, and it happens to a lot of people...maybe I'll put the other VVT mechanism from the dead engine on and see if it quiets it down, but at least now I know it's not doing any harm to the engine. And unfortunately, I found out that I'm hitting WOT, so that's not my problem with VVT not coming on. However, Exile pointed out a shop in Seattle called Intec Racing...they've done quite the silvertop 4A-GE swap on an AE86, and I'm going to ask them about my VVT to see if they've got any good ideas.
