got oil leaks and o2 sensors failing? it might be YOUR FAULT!

[grumpyvette]

you might also keep in mind that alot of guys (mostly the older guys that refuse to read labels )use sealants and gasket sealers that are WRONG for the applications they use them for, EXAMPLE
that yellow slime (3M Weatherstrip Adhesive(item#51135). Ive also heard it refered to as "gorillia snot". that yellow contact glue like sealant is used by many guys to install valve cover gaskets, and oil pan seals/gaskets, well it was NEVER meant to be in direct constant contact with hot oil and while it will work with most mineral base oil in that application I can tell you from seeing many examples that some synthetic oils slowly desolve it over several months time , since it was never designed for that application ,you can,t blame the product! but Ive seen numerous cases where engines leaked constantly after several months once synthetic oil was used in engines using it as a gasket glue.
just for your info 3M makes a better Weatherstrip Adhesive (black) #08011, part no. 051135, "a black-colored, high-strength adhesive for adhering rubber weatherstripping and gaskets to doors, windshields, trunklids, windows, and lights."


btw while we are on the subject some sealants leach by-products into the oil that cause the O2 sensors on EFI engines to fail, look for the SENSOR SAFE sealants

Excellent resistance to hot oil. Non corrosive to metal. Oxygen sensor safe.

Thanks Grumpy. That's one thing my builder always stresses, I'm glad you pointed it out.

Good, very informative post, but age has nothing to do with reading labels. I am an avid reader of labels and instructions and I've known many, OF ALL AGES, who are not.

How about leaving the age discrimination behind.

Have a great day,

I AM one of the older guys and I can assure you that after many years of working with other engine builders , and watching quick repairs at race tracks between runs that the older guys tend to be more set in thier ways of doing things and less likely to read lables, now that does not mean all of us but I see more older guys than the younger guys that just use sealants that they have used successfully for years even though the requirements may have changed.
this in no way referes to every old guy,but I learned the hard way and so have many of my OLDER FRIENDS, while the younger guys who are less sure of the proccesses involved tend to ask questions before blasting thru a job they have done dozens of times
watch the older guys in any auto parts store select gasket sealants, most take only second to grab several, the younger guys stop and READ the labels and applications, now Im sure thats mostly because we as older guys have read the labels previously but in some cases the product formulas have changed (IMPROVED?) or warning that were added after years of use have changed

Woh, take it easy, Doc. Grumpy meant nothing by it. No use in making a big deal out of something like that.

It often happens when reading written text that a meaning is heard that was not meant. When I read this it came across as I indicated.

I apologize for my harsh response.

Have a great day,

So then can I infer that should I go to synthetic rather than the dino I now use that I may experience leakage, depending on what the previous owner(s) of my car may have done?
Maybe I should stick with the dino...
