Just drive it alot when done cleaning it. Make sure it gets good and hot and stays that way for a bit. Ive used gunk on lots of cars, never in nutty quantities, and never had any issues. I also would never spray anything inside the belt covers or allow anything to get on the belts or cam bearing area. I can see how cleaning of the engine with a product like gunk could be bad if after cleaning the wet engine was just allowed to sit. Then again, its been my experience that sitting is about the worst thing to do to a car anyhow. | ||

I have found that spraying WD40 heavily on the engine and letting it set for 15 minutes then taking a spray bottle with half dishwashing detergent and half water, soak the engine down on top of the WD40. After another 15 minutes pressure wash with a high pressure hose nozzle and a garden hose or better yet use a pressure washer to remove all the grease etc.. It will not remove the paint on the engine and cleans extremely well. | ||

I've use a product called Simple Green to clean/degrease engines and such. It's bio-degradable and doesn't seem to be caustic at all. A rinse with clear water either from a hose, if it's doable, or a spray bottle really cleans 'stuff' up. Of course what's coming off the parts you're cleaning is another story! | ||

Degreasers can be pretty caustic and may attack the rubber seals if left undiluted, ie. not throughly rinsed off, for a period of time (probably weeks). It's more likey the PO used a pressure washer or steam cleaner that had enough power to blast water past the seal. Been There, Done That. I pressure washed my Audi transaxle that I had removed during a clutch change and sure enough 6 months later the axle bearings just inside of the inner CV joint started growling. Moisture had rusted the bearings near the seal. | ||

The berings on the trans that failed are the outer carrier berings next to the drive shaft. the gunk ate the seals and the subsequent washings let water into the trans Paul, I am sure as you know you trans is not topped off with gear oil, its filled a little over half way so theres plenty of room for water inside These parts where not falling apart with rust,it had just enough to cause the berings to fail eventually. My 328 has no salvage title, and according to Bill @ Enzo Motors is one of the most perfect running, and cosmetically nice 328s, he has ever worked on, which he has done from 1990 to 1999 and he clearly remembers my car and it PO, I am not a customer of his so he has no reason to exaggerate my car or any prior work history hes done These are similar comments from other shops I have taken my car to here currently Believe what you want its your car | ||

If this car had a salvage title and were flooded all this would make sense. Now if the guy were using Brake Cleaner I could see this happen...I have seen brake cleaner attack seals...it is very effective at removing grease...oh...and cleaning your clothes...it's the stuff that dry cleaners use...hmmm...how safe can that be. | ||

Rusted out parts in the transmission? where did all the 75/90 weight oil go? I never questioned the front cam drive sealed bearings having their front seals fail as they are exposed to the elements and naturally do fail over time as do those particular bearings but the story as a whole does not hold water (no pun intended). If the bearings rusted then the cam drives would have seized which would have caused great damage to front timming cover and possible cam & valve train damage long before the the incredible amount of water could enter tranny and engine and rust up parts. I would like to know what seals on Tranny were destroyed by GUNK and water as I have pulled my tranny out and apart several times and there are no exposed seals. The gear shift seal on outside seals engine oil sump and the only other outside seals would be the two inner CV Boots. How do you get water into the tranny with a garden hose? | ||

I could see the Gunk engine cleaner hardning a seal and promoting premature failure... perhaps. Rust might be a by-product of removing any oil that may have built up on the idler bearing surface, allowing the steel surface to then rust. The grease seals on the OEM idler bearings are not that great to start with, so I guess an excess use might lead to the eventual removal of the grease from the bearings. Hmm. I'm still skeptical. I guess the key here is moderation. BTW, I use foamy engine brite. No problems thus far, and I really do use my cars to their limits. I do, however, avoid spraying anything in the cam belt area, since I really don't know what the belts will like or dislike. Early 308's and Early TRs, 512bbi's, etc. did not have the protective inner covers. | ||

Attached #35 is the bering that failed, there is no seal on the outside of the motor for this bering only a retaining ring  | ||

I suppose it is possible, the two bearings outter bearings on the cam-drive gears are not lubed and can be rusted. But, that means the seals must have gone first. Highly unlikely. Why would they replace the rod bearings? Why should I pay for unecessary work? Sounds like a boat payment that the dealer needed to make. | ||

Pure nonsense, rusted bearings on a 328 from washing the engines. Be careful next he tell you an oil change costs $1500. | ||

David, I guess they way the engine is designed there are some berings on the front of the case where the gears that drive the cam belts are on the out side of the engine, the Gunk will flow into them while rinsing it off the motor | ||

Jeff, not that I know what I'm talking about here, but if Gunk, or any other substance got into a bearing wouldn't that indicate that you had a bad seal to begin with..... Rusted Bearings??? | ||

Going over my old service records on my 328 Enzo Motors in Anaheim CA removed the engine and trans to replace the front bearings on the motor and disassmebled the trans to cleanout rust and replaced destroyed bearings there also. After speaking with Bill the owner of Enzo repair shop he mentioned the PO was a fanatic and used Gunk a lot to clean the engine, the gunk dripped down to the lower front berings on the engine and rusted/destroyed them, it also destroyed the seals on the trans and let water get into it which rusted out parts and destroyed berings there also,since they had the motor out at the time they replaced the rod berings also, the mains where perfect though, the car at the time had 36k on it $4500.00 bill for a few 2.00 cans of Gunk |
