Seafoam use?
Hey guys. This might be a stupid question.. But how do I use seafoam? My oil pressure is really high so I'm going to use seafoam to see if I can't loosen the oil and I will do an oil change after I use it.. But how do I go about using it?

Re: Seafoam use?
First off...how high is too high? My car starts at about 60 and as it warms up goes down to 35-40 while cruising, 30 at idle. I run 10-30 Rotella oil in it.

It's constantly around 60, even at NOT.. Except when I floor it and let off the gas, it blips down to around 30 and then shoots back up.

Re: Seafoam use?
yeah, sounds like your gauge is off, the factory gauges are known to be all over the place
but to answer your seafoam question, suck it in through a vacuum port, pour some in the gas tank and add some to your oil
sucking it through a vacuum port will stall the engine if you give it too much so go slow

Re: Seafoam use?
Could be your sender unit too. My gauge would peg high and sometimes jump erratically.
Replaced the sender unit and it fixed it.

Re: Seafoam use?
Where is the sender located at? I could hopefully buy the part pretty cheap and maybe fix it?

Re: Seafoam use?
seafoam will do little if anything for your oil press. problem . your problem is the oil press. sensor . easy to change , located just above the oil filter . you said you had a 5.7 vortec engine . who did the swap ? has it ever read normal ? my guess would be sensor bad or not even hooked up or installed . good luck .

Re: Seafoam use?
The swap was done before I bought the car. It had a v8 in it before, I do know that. I never checked when I first got the car, but about 20 miles of driving, a SES light came on and I am unsure as to what that is from.. But I will check this weekend if the sender is connected or not. I will let you know if you guys are ok with that.. If I have any more trouble. Haha
