Ok I am about to start ripping my car apart and rebuilding it from the ground up. I am goin to build the motor, suspension, new paint, everything. But my question is what is the best way to clean my block? cause its pretty dirty and i wanna make sure its really clean before i start to reassembly the motor and dirt fills into my motor from the outside. This may be the wrong place to post this, so if it is let me know and i will redo it. Thanks

 

I'd recommend having it hot-tanked.

 

yea def hot tanked and I would consider honing it some, best bet is to take it to a cnc machine shop, they will take care of it for a resonable price! Best of luck

 

Ok thanks alot should i disassemble it and take it to them? or let them do it?

 

they would probably make you take it apart

 

ok thanks alot everyone for your help

 

yea, they normally won't disassemble a block, they will make you do it. Its pretty easy, just when you do it, have a lot of plastic baggies so you can label all your bolts and **** so you know where EVERYTHING goes. you dont wanna put **** in the wrong place, also have a torque wrench handy.

 

yea i know i have worked on a few motors before and u learn to label **** or u will expletive it up big time. and yes not onyl have a torque wrench but a service manual LOL. but thanks alot for the info

 

if thats not possible you might try a pressure washer, one with a kerosene heater...i detail cars and we have one that gets about 300 deg. and will take off paint...just a alternative

later

 

good idea too.

What exactly is this? Can someone please explain it to me?

 

its essentially have hte block put in a high power dishwashers for metal parts. It uses a detergent and will clean the block really well.

 

yea my uncle a few years back thought about buying one for his shop but he didnt. never thought he would have much use for one.

 

cheap way is pressure wash. then use a blow gun to blow dry. prevents rusting. you also def need to hone cylinders. new rings will never seat right

 

hot tanking is the best, pay the $ and do it...hey as in honing the block..what exactly is it, and why will it never sit right?

its called crossthatch

 

I usually cover mine in simple green and scrub it in real good, then let it sit for a couple of hours. Repeat five or six times and then hit it with the pressure washer.

 

thanks alot for everyone's input, but it sounds like hot tanking it is the best option not cheapest but bestest. and i only wanna do the best for this motor.

dude i am talkin about cleaning my block not my build. altho yes i am goin to resleeve it cause i am boring it to a 84mm bore.

It's called Cross Hatch and the lines are at 60 degrees to make the piston rings seat. 26 hp lawnmower sounds pretty fun. Almost like a redneck family re-union. Hoppin on the old john deer go kart! YEE HAAA.


Anyways this guy that is hot tanking his block knows what hes doin. So anyways, that was what this thread was all about in the first place. So yea Hot taking sounds good. I'm actually looking for places to hot tank and hone around my area. I'm buying a b16a swap for a grand and strippin her down and giving it a nice fresh rebuild so I can boost it to run well lets say 2 bar and smoke a lot of ****! But yea before you hone it hot tank it! you need to have it honed after so the rings seat! make sure that the cylinder sleeves are coated to prevent rust.


Does anyone know how much it would cost to Hot Tank and Hone it while they are at it? Need to get some prices going here, I'm already at $3,500 for this rebuild with a turbo and internals minus valvetrain Everything is so ****** expensive!


My estimate is 300whp or better!

 

on mine, i used Castrol Super Clean (this **** is wayyyyy better than simple green) and a wire cup brush with an air powered die grinder to get into the really dirty places.

after scrubbing and washing, use your air gun to make sure everything is dry and spray paint the block with VHT high temp paint. i used the "flat aluminum" and everybody that seen it thought i bought a brand new block.

VHT Flame Proof Coating

Part Number SP-117 Flat Aluminum
