Changing Oil Type
 

Ive Read alot of other posts about Seafoam and Synthetic Oil So heres my Question, I Beleive I have a slight Intake Manifold Exterior leak, i can see a lil bit of it. My Oil levels are fine my antifreeze gets a little dirty and i top it up but other than that its fine, Now I Want to seafoam my Intake and Possibly my Crankcase as well. My Truck has 126,558 miles on it. Had Everything Tuned up in April 08. I want to seafoam it and the switch to amsoil 10w-30 Synthtic Oil. If I seafoam it will it cause more damage and secondly can i switch to syn next oil change?

I would get the intake manifiold gasket replaced prior to doing the Seafoam and, yes, you can switch to syn oil after it's all done.

Any Chance it will leak more and worse if i seafoam before I change the gasket?

RE: Changing Oil Type
 

I would say it is possible. Who knows?

i see, well ill tackle that when the weather gets warmer, ill do a seafoam treatment a couple of times to clean all the crap out then flush the Heater Core And Radiator and change the Manifold and Head Gaskets

I run mobil1 10w-30 in my 98 4.3 blazer... I change the oil every 10k and the filter every 5k. Swapped it over to synthetics at 90K miles and now at 120k... so far no leaks.
