After some cleaning I noticed that 3 (so far) of the piston faces/tops have a little knick in them at roughly the same spot. The valves don't show any sign of damage, and maybe these are nothing. Is this anything to be concerned about? Here's a pic of the deepest one (upper right side of pic):

 

A future job for me, has anyone done it on a 95? I'm gonna do the oil pump gasket to.

Mandy ran hot today, fan clutch is new, t-stat is new, water pump new. Only thing was 1 ac condenser was working before, now both are out. I have one replacement, now gonna need another.

I knew this day would come, good thing my 4runner runs good. Mandy is gonna be down for a while

 

I noticed that when I got my heads back from the machine shop they were still pretty dirty in each of the ports. I can put my finger in and pull off chunks of crud (maybe his chems are getting old). Is is safe to shoot carb cleaner in those ports? I saw a trick where a guy used a small hose on the end of his shop vac to vacuum out the cleaner and gunk. Is it going to hurt anything? The heads are obviously not back on the truck yet.

 

Maybe a bottle brush style brush. From heads turned on side so work from bottom, gravity makes crud fall out. Vac. Then brake cleaner or carb clearner. But don't suck carb cleaner into shop vac, can make vac motor catch fire.....

 

Thanks Savannah. Anybody know what loctite (or similar) to use on the front cover/water pump bolts? What about the oil sump?

 

Loctite Blue.

 

Hondabond works well also.

 

Hondabond is good stuff.

 

I'm surprised they didn't clean the entire thing? The shop that work on my engines always cleans everything and puts them in plastic bags. Here is the last head he did for me......CLEAN.....



When cleaning a head or piston, use a popsicle stick to clean the crud that is caked on there. And make sure you wash the entire head with soap and water. Then dry it out with air pressure.

 

Ditto on the Hondabond....UltraGrey will give you the same results...
