Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem. In this video I outline the basic valve job procedure. Cleaning the valves, cleaning the seats, cleaning the combustion chamber and lapping the valves in to make a better seal. Here I cover the process start-to-finish. It's the same exact process for pretty much all non-rotary combustion engines. It takes patience and perseverance to do this job, but anyone can do it. Reference your service manual for measurements and service limits. Everything else that's not in your service manual is in this video. I apologize for not having broken busted crap to work with in this video. It's more beneficial to all of you when bad fortune falls on me because it gets well documented, and many people watching these videos are looking for answers. If you have bent valves, you will discover it quickly once you chuck one up in the drill. You'll see the face of the valve wobble around while it spins. You'll see evidence of this damage on the valve seat. If it's bad, you may see damage on the valve guides in the form of cracks or missing pieces where the valve guides protrude through the head ports. Give all that stuff a good visual inspection. ...and if you doubt yourself, never hesitate to get a second opinion or consult a machine shop. They will have access to expensive tools that you wont find in your average gearhead's garage.

What i use to polish cylinder heads and intake manifolds
Join me on Facebook! www.facebook.com/omgitsmrmack Just showing your guys how we go about polishing and getting the beautiful finishes after its all said and done.. this method takes some skill.. some might say i make it look easy.. at 14000rpm the grinder i use is not a joke and has hurt people when they dont use it properly.. when the paper unloads on a long rod it tends to bend the rod at a 90 degree angle and if the user freaks out and does not hold it away and let it slow down then they end up with a nice big sliced up arm or mid section.. i myself have bent a few in my time and lucky for my i have a quick reflex and manage to hold it away without hurting myself..

11 Second Nissan 240SX SR20DET Dyno Runs
!!!!! - DO NOTE VISIT THE WEBSITE AT THE END - !!!!! I no longer own that website, and it was made into a porn site. I have no affiliation with it!!! I wanted to get a baseline Dyno run in before installing my built motor. This is a completely stock SR20DET with a larger turbo, injectors and supporting mods. Stock cams, stock head gasket, everything inside is OEM. It also has a very poor tune, one other reason why it has low numbers. However, I did manage to run an 11.95 @ 114 MPH with this setup so far...





DIY: Porting & Polishing a Throttle Body
Video tutorial on how to port and polish a vehicle's throttle body. In order to do this procedure, you must remove the throttle body from the engine so you can probably polish and port the throttle body and the material shavings do not enter the engine. This isn't much of a horsepower increase if any, but it does help with throttle response. Do not remove any material from around where the throttle plate touches in the bore either. Also when doing this procedure, I would recommend purchasing a new throttle body gasket so you won't have any vacuum leaks once reinstalling. Make sure you don't take off too much material either where it will affect the structural integrity of the throttle body. When doing this type of work, make sure you wear safety glasses for your own person protection. This particular tutorial was done on a 1997 BMW 540i. Procedure: -remove the throttle body from the vehicle -clean any oily build-up inside of the throttle body -remove the butterfly from the throttle body, most are held in with 2 screws that go into the shaft -if you can, also remove the shaft and linkage (some shafts are pressed into bearings, other are not) -if you can't remove the shaft, no big deal you just have to work around it -tape around the shaft or the hole where the shaft was so no metal shavings get into that area and cause premature wear for the bushings or bearings -depending on the finish of the throttle body's bore, there may be edges which you can to smooth out -in order to smooth out those edges, you can use grinding stones for either a drill or rotary tool such as a Dremel -when using a grinding stone, it's best to use WD-40 penetrating oil with it so the aluminum material doesn't plug up the stone and it'll no longer cut away any material -once you are satisfied with the sharper edges being ground down, you can down move onto sanding drums for the rotary tool -you can also flare out the bore where the air enters slightly so it has a smoother air flow into the throttle body -you can even port match the throttle body to the intake if the throttle body is smaller -if you don't have access to a rotary tool and sanding drums, you can also use flap wheel drum sanders that can be used on a drill -the flap wheel drum sanders are available in a variety of grits such as 40, 50, 60, 80, 120, 180, 240, and 320 -when using the flap wheel drum sander, you can add water to help with finer sanding as to keep the dust down -if the surface isn't too porous such as what is shown in the video, start out with a finer grit like 120 and move your way up -once you have reached the highest grit in a flap wheel drum sander, you can now do some sanding by hand with 400 grit and add some water for lubrication -once satisfied with your product, you can now move up to an abrasive like Scotch Brite -depending on the color, will depending on how course the abrasive pad material is -I started out with green and then moved onto the red pad for the finest compound -you can also use water with this too to help finer sanding and to keep the dust down -again once you are satisfied, you can now move onto a metal polishing compound -the metal polishing compound I would recommend is Eagle One -apply the polishing compound paste and rub until highly mirrored finish (multiple coats can be applied to achieve a higher polished surface -once you are done with the bore, you can now move onto the throttle plate -most throttle plates are smooth to begin with so you can skip directly to the Scotch Brite stage using the same procedure and finally move onto the metal polishing compound -once done, you are ready to reassemble the throttle body -make sure you peen the thread of the screws on the other side to ensure they don't come out or apply Lock Tight thread sealant -install new throttle body gasket along with throttle body to your vehicle Thank you to all those who watch my videos and support my content.
