Clear RTV on engine?

[Mishakol129]

Just a quick question. I assembled the F23 short block and want to know if its okay to use clear RTV on the engine. I used it on the oil pump. The Permatex website says that its "not recommended" for engine gasket applications, but will it be fine to use it? I already installed the oil pan and I don't really want to change it, its just I want to know if it work or not.

You answered your own question....

I didn't really want to hear that. Even though the site says that, it can't be the whole truth. Someone who has used it or knows if its alright to use there should chime in, I really don't want to do it again.

Haven't learned your lesson on RTV yet? The manufacturer is telling you it's not meant for the purpose that you are using it for. What more do you need? Don't half ass it, do it right.

Let's actually use some facts to explain this...

Did you put it on the oil pump or oil pan? Your post says both.

The clear RTV is similar to what you should use, but doesn't have the same properties. It is not as resistant to oil as it should be. In addition, its effective temperature range is -75 to 400 degrees fahrenheit while other sealants effective temperature range goes up to 600.

I am not sure how hot the areas you might have put it on actually get. However, seeing as how it is not as resistant to oil, I probably wouldn't have used it if I were you. I'd recommend changing it soon, but I don't really see it causing too much damage to drive like that till you can fix it correctly.

I have the engine on a stand and used the clear RTV on both the rear main seal and the oil pump. I also used it on the bolts. I just don't want to have to do it again and this thread was trying to ask if I can safely use the clear instead of the other stuff.

Looks like I can't. Dang it. I need more wire wheels to remove the gasket material too. Guess I need to stop bitching and do it. Alright, thanks guys.

Do you recommend the black or the gray?

OEM calls for grey. Some people use the black for the oil pump.

Okay, got this. Thanks. The purpose of this thread was actually to see if I could "get away" with using the clear RTV. I already sealed the oil pump and rear main cover, I want to know that if anyone knows for sure if this will work. On my old rebuilt engine I used clear on the rear main cover and its holding up fine after 30,000 miles. I don't know what the long terms effects of this will be though. I just don't want to have to go in and do it all again, its time consuming.

I don't want to do it all again if what I had on there to begin with was alright for the job. I had used the clear to begin with because I personally felt that it would.

If you don't want to tear it down to do it again then do it right the first time. Only will set you back a day, its no big deal.

Just the other week I had a feeling I put in these cam seals to far. After a day of thinking I looked beyond it and put my new timing belt. Right when I started the car it started to leak and ruined my belt.

I had to buy a new belt, and new seals.

Trust me, just do it again. Use Toyota FPIG black sealant, or Honda bond. Grey permatex is good but once you use that oem stuff you never go back.

You know that tag on hair dryers, curling irons and such that warn you not to use in the bath? Pay no attention to that. There's nothing like enjoying fresh toast while in the shower.

Seriously, do it right the first time.
