i'm not exactly fond of additives. i have seen pictoral tests of these additives and it severely tampers with the anti-foaming ratio in the oil. once you add additive, the oil is "diluted" into a mix that containes an incorrect ratio of standard anti-foaming additives and it gets filled with air and wont cling like normal.
it may be a good concept, but oil companies spend lots of time and money researching what they produce, and "playing chemist" (as the article i am referring from states), is not a good thing to do unless you know really know what you're doing. i dont have the link on my right now. let me know if you'd like to see side-by-side visible oil tests showing the clinging and foaming properties before and after additives.

i'd look at it. I haven't really ever heard a mechanic that said...., Don't use lucas. I am inclined to be a dick and say you must like the rod nock but you don't deserve that especially sinse you took the time to research it. I would add lucas and not look back. To each there own I guess. But for sure. I would check out that site.
Don't use Lucas, it may be okay in a V8 with a million miles on it, but in a turbo charged engine, the super thick Lucas does nothing but foam, and not lubricate.
I wouldn't do it.

yes that is exactly the site i was referring to. bad results and i will probably never use the stuff unless i somehow get a horrible engine that has no other hope. lol. thanks for the idea though. my engine sounds better now... and i noticed the noise is worse with the clutch depressed so maybe a throwout bearing or something...not sure.
either way, all i have now is a little coolant leak i cant seem to find. i had one where the heater hose goes into the firewall...i didn't clamp it on. but i think i still have a bit of a leak, it's back by the rear suspension arm!!! i dont know how coolant got there, but it did! if anyone has an idea as where coolant might be leaking from or how it got clear to almost the rear tires let me know. it think it just went inside the frame or something.

You need to pressure test the system. You can either have a shop do it, or you can rent the tool from Autozone/Napa. Pressurize the system to ~21psi, and look around for leaks. It should be VERY apparent at those pressures.
get your black light dye at o'rielly's. It's a 2 shot package. Put it in and drive it for a few miles and keep checking under it with the black light. You may even want to go to the automatic car wash and clean the belly of the beast before insertion, or right after.
I think this would be the least expensive way to find your leak, if my other redderick didn't phase you.

john- thanks. i might end up trying that. i have an air compressor so maybe...just maybe...i can do this myself. i dont want to bust a leak though...whatever it is HAS to be a loose hose i didnt crimp enough. no leaks before BHG fix....so its my fault i think. i'm thinking it might be the rear water hose...i was cautious not to over-crimp and cut the hoses with the clamps so maybe its not tight enough. but the hoses that run along the oil filter side of the block (metal tubes) look wet...but they are greasy so i'm not sure what it is. the drip runs down to the bottom of the engine where it meets the tranny and there is also a drip by the rear tire still... i'm hoping its just left over from the last leak.
either way, i've narrowed it down and eliminated that other leak so now its minor... few drips after each run so its much slower than before. just as long as it doesnt take a dump while i'm running.
supra- the die is a good idea but i think i can find it without that...i know where most if not all of the lines run, i just have to analyze caferfully enough and get some good mirrors. my firewall is shiny wet so i think its up high. unless thats just oil.
I have a pressure washer, i will wash the car this weekend underneath if i can, if not i'll be taking it to a garage with a lift with my friend and i'll search for the leak from beneath. only problem is i cant touch anything with my hands (hot).
thanks again guys. i'll be posting still but slower because its pretty much done and school has started.
