Hello.
Sorry for my bad english  My 7afe have been smoking blue smoke for some time now.. and the smell of oil is present almost all time (USE ALOT OF OIL!)... It smokes never when idle, only when i give it some trotle. i have been thinking it may be the Valve seals, but it might be the piston rings aswell... what is your opinion? |

The head will get cleaned when you have it resurfaced. You need standard twelve point sockets for the head bolts. Normally 6 point sockets are recommended for hex bolts because they are less likely to round a bolt head off, but I believe a 12 point bolt head and matching socket have more surface area in contact so this is likely why toyota picked it.
You should check the clearances of the cylinder bores before you put new rings in, they will tend to become out of round in the directions the crank rotates and can develop a taper(wider at the top or bottom) from the force of the piston rod. Take measurements on the top, center and bottom of the cylinder both parallel and perpendicular with the length of the engine, if your unsure then take the block to the shop and have them check and or hone the bores. I second checking and replacing worn rod/main bearings. Couple $s worth of plastigauge since you already have the lower end apart, money well spent. Make sure the machine shop shims the valves properly, if you provide them with the camshafts and cam bearing caps they can do this for you. You WILL need a head gasket. You SHOULD get- head bolts ($20, they are torque to yeild which means they stretch and are not intended for reuse) Full gasket set or head gasket set. It will contain all the gaskets for the engine except perhaps fuel injector orings You COULD get- Timing belt, its a non interference engine so you can drive it till it snaps without damaging the motor. Water pump, while you have the motor apart its easy to replace Oil pump, shouldnt wear but the tolerances can get out of spec, you want to oil your new motor properly right? Im sure Im forgetting a lot but there is some info to munch on... This post has been edited by Special_Edy: Jul 10, 2014 - 5:05 PM |
