Cylinder Heads, Cam and Valve Train

Cylinder Heads, Cam and Valve Train

Engine Parts and Components:

Yes we build complete engines for all years of 1600, 2002, 320I, and E30 318I. Anything from a stock rebuild to a 300+ HP Turbocharged Monster.

  
 

All our engines are built to order. We are not a production engine rebuilder. All engines are treated as individual projects and afforded the attention needed to make then outlast and outperform any other engine available. We prefer to build the engine core that was in your car, but we will supply engines on an outright No-Core basis when the need arises.

All Top-End Performance engines, from stock to GT Road race, go through the same basic processes. We do not cut corners.

After Disassembly

All cylinder heads are pressure tested and inspected for cracks.

Although we can successfully repair cracked heads we prefer to just get another casting to work with. We reserve the crack repairs for special heads that are difficult to replace or have so much money invested in modifications already that it is more practical to repair them then scrap them

  • All Engine blocks are Hot Tanked and Magnafluxed for cracks.
  • Cranks are cleaned and measured for journal size and roundness.
  • Con rods are check for straightness and magnafluxed for cracks.
  • We are clean freaks when it comes to engines.
  • All parts are hot tanked or cold tanked as needed.
  • All blocks are scrubbed and brushed out
  • All blocks get new Freeze plugs installed
  • All blocks are painted with high quality engine enamel
  • All Aluminum parts are bead blasted to look as new as possible.

 

We do not paint Aluminum parts like heads, timing covers, oil filter housings, etc.

We do offer various coatings for valve covers depending on what you want.

Since we replace everything else the inspection process is not that tough.

All block assemblies get .

  • NEW JE Low Expansion Forged 2618 Alloy pistons in an oversize and compression ratio of your choice
  • New Total-Seal or Standard Plasma-Moly Piston rings
  • New Kolbenschmidt Rod and Main bearings
  • New German Oil Pump and pump drive gear
  • New German Timing and Oil pump chains. ( Non-Master link style )
  • New guide and tensioner rails
  • New Rod Bolts and Nuts
  • New Head bolts ( Or ARP Head studs if requested )
  • New German Water pump
  • We use only German Gaskets and Seals

 

All cylinder heads get

  • All new valve guides ( Late model guides that accept Viton small diameter seals. )
  • New valves as needed

 

On stock engines. Performance engines get all new Stainless Steel valves.

  • Valve seats as needed
  • New Rocker Shafts
  • New Rocker Arms
  • New Valve springs

 

Either stock or dual performance springs

  • Reground camshaft

 

Either stock or your choice of performance grinds.

Rebuilt Cylinder Heads (Using your core)

All our heads are rebuilt the same way. 100% complete. Heads are disassembled, Bead Blasted and Pressure tested. Cracked heads can be repaired but it is usually cheaper and easier to use a different casting. All New valve guides (All M10 heads get late style E21 guides that use the good small seals..) Are installed. Seats and valves are replaced as needed. 3 angle valve job with hand lap and back-cut. Surfaced top and bottom with the upper front cover to insure a leak free installation . All new Rocker Arms, Rocker shafts and Dual valve springs. Reground cam with your choice of 282, 288, 294, or stock camshafts. Assembled with Viton valve stem seals. Includes the complete head gasket set.

Yes we can supply cores and sell heads on an outright basis if your core is junk. Core head price varies with current supply. It averages $250.00 for a 121, E12, E21, or 1.8i head. If we are building the engine we always prefer using the E12 or 1.8i head castings .

 

Camshafts

All our cams are available either as re-ground on stock cores or as NEW Billets. The 302, 316 and 328 require the use of lash caps.

All reground cams are sold on an exchange basis with a $100.00 core charge if we happen to have a core available in stock. We can also grind your core. Turnaround time on cam grinding is 3-4 days.
