sticky lifters or whatnot? SEAFOAM!!

[KStretch55]

Ok, after hearing so much good stuff about Seafoam and MMO, here's what I did:

 

I did the Seafoam treatment, 1/2 can in the full tank, 1/2 can in the crankcase and maybe a 1/4 cup sucked through direct intake vacuum line. Drove it about 150 miles and changed the oil and filter. Refilled with 4 qts of good quality 10W-40 and 6-8oz of MMO.

 

I think it definitely must have loosened things up cuz' before I only had some lifter pecking on start up and it quit once she was warmed up. Now, sounds like the lifters are taking turns talking to each other! One will peck for a bit, then another, then they'll be quiet for a while, then start around again. Even when it's warmed up. Could be that the process has broken a lot of varnish and carbon loose and as the bits and pieces work through the system they clog the weep holes on the lifters a bit. I'll give it some time to catch any gunk in the oil filter. If it doesn't improve soon though I'll probably add some 4cyl. STP and see if that makes them less talkative. Might omit the MMO next oil change. Any thoughts?

Well my thought is that 10W oil might be too thin. I did say might. You can chase down what the engine likes as a minimum weight by going to a single weight oil. Just a thought as I've had success with this method.
