Here at Motor Mission we have the equipment and expertise to perform not only machine work on engines and cylinder heads but also custom and one off parts machining as well. From gas engines to diesel engines, both foreign and domestic as well as cast iron and aluminum pieces and parts as well. We have [...]

This is a DDC DD15 Detroit diesel cylinder head that came in to get checked out. After cleaning it in the hot tank we'll magnaflux it for cracks. If no visual carcks can be seen or detected we will pressure test it for leaks. The engine is getting an in-frame rebuild so our customer just [...]

Here's a pair of high performance aluminum cylinder heads we got in for a 496 cubic inch big block Chevy stroker engine we're building. These heads are a good and much cheaper alternative to some of the higher end cylinder heads that are available. They offer the advantages of lightweight aluminum, large valves, and rectangle [...]

Here's some pics of a Pontiac GTO 389 cubic inch V8 crankshaft that we did a grind and polish to. The crankshaft came in with some heavy scratch marks on both the rod and main journals so we ground and polished them to the next undersize for the fitment of some new oversized rod and [...]

Here's some engine goodies we received for one of the big block Chevy stroker engine builds we're working on. These parts are for a 505 cubic inch engine we're building that will be going into a 1969 Chevelle. In the pics is a Milodon aluminum timing cover, a set of World Products Merlin III cylinder [...]

Here's a couple of Harley Davidson motorcycle cylinder heads we rebuilt. These Harley heads were brought in for a good cleaning after what looked like a major sandstorm got all up in their junk. We ended up doing a complete valve job along with milling their surfaces square and flat before reasssembling them with new [...]

Here's some import engine and cylinder head machining we finished up. The four cylinder block, crankshaft, connecting rods and cylinder head are made by Toyota. We did a bore and hone to the cylinders for new oversize pistons and rings, surfaced/squared the deck of the block, did a grind & polish to the crank, reconditioned [...]

Here's some pics of a set of high performance aluminum cylinder heads we ordered in for a 555 (Triple Nickel) cubic inch big block Chevy stroker engine we're building. We special ordered the heads from AFR (Air Flow Research) as a complete assembled set for a hydraulic roller camshaft and valvetrain. The heads are fully [...]

Here's some before and after pics of an aluminum cylinder head that came in for repair. The cylinder head is for a 450 KTM four stroke motorcycle. The valve seats were slightly pitted so we machined the intake and exhaust seats with our three angle valve seat cutters on our Tobin Arp seat-and-guide machine for [...]

Here's a 3306 Caterpillar crankshaft that came in for machine work. We cleaned it up in our hot tank and then checked it to make sure it was at the proper hardness before wet magging it in our wet magnaflux for cracks. The journals were then all measured with our Mitutoyo micrometers. Both the rod [...]
