Valve Medic


I bought a bottle of Valve Medic for my 92 Wrangler 2.5L. The oil pressure was running super high (usually 45, now 60) and I thought I'd try to unclog some of the passageways with some Valve Medic (a strong detergent from Gunk). Has anyone had any bad (or good) experiences with this product?

Been a few days..... How'd it work for ya ?

Before I changed oil last time I poured in a can of Sea Foam....Ran it for 100 miles, drained the oil. Didn't see any difference ,oil was still clean..
In the old days of Chebby's and Olds mobubbles I used a quart of Auto Trans Fluid to flush out engines before I tore em down.. It seemed to work pretty good on the sludge of those old engines.
With todays oil and regular oil and filter changes, you shouldn't have any plugged up passages ... "BH"

Mechanic in a can seldom works. The only way I will use it is if when I open the can and look inside I see a little man dressed in coveralls with tools and parts in his hand. Been around the car biz since 1969 and I have seen very few of these products do any long term good.ATF before an oil change has been around a while and it works its not real agressive, flushes and Seafoam are too agressive and can plug up pickup screens and passages. There is no substitute for regular maintanince

I don't remember who it was that said it, one of the old school racers or engine builders, but, when asked about additives, he said "you can pour it on the ground or pour it in your engine, it has the same effect either way".
