Our engine rebuilds are thorough and extensive.
The Rebuild Process
The engine is stripped to bare components and put into a high pressure wash at high temperature with cleansing chemicals, this removes all carbon deposits and debris from previous failures. From this stage the Cylinder bores and pistons are checked for cracks and wear tolerances. If your returned engine core requires cylinder re-sleeving this will be completed at an extra cost.
Pistons are checked and Rings are then changed, Connecting Rods and Crankshaft are checked for tolerance specs.
Upgraded Main & Rod Bearings. Available only at Vertex Automotive
The Rod and Main bearings are replaced with EPS bearing shells that are 15% wider than stock, for a stronger and more durable bottom end. The main bearing shell at the flywheel side is replaced with the EPS Wider Double Friction shell for stronger crank support. This is an industry first and is only available at Vertex Automotive
The Oil Pump is reconditioned and scavenger pumps checked and replaced if necessary.
We then address the infamous IMS and permanently correct it using the revolutionary ETERNAL FIX by EPS
The IMS is machined for larger cylindrical roller bearing, (ETERNAL FIX).
The IMS is then modified for front oil pressure feed to the IMS bearing (Patent Pending)
Why do we use the ETERNAL FIX with Cylindrical Bearings with Thrust Control?
Cylindrical Bearings have very high load bearing capacity, 5 times more than Ball Bearing. Cylindrical Bearings are used in, High Temp & Low Viscosity Lubrication such as Automatic Transmissions. They can carry extreme lateral pressure without wear to the friction surfaces. This is because the bearing friction surface is flat and not concave.
Cylinder Head Rebuild Process
Each cylinder head core is disassembled and inspected for broken bolts, stripped thread holes and broken mounting holes, etc. All heads go through a three-step cleaning process which includes:
1) Passing through a high temperature oven.
2) Professionally bead blasted.
3) Placement in a non-caustic hot tank.
The Head is then inspected for cracks & pressure tested. Cam bores are checked for spec and honed if needed.
The machining process includes;
? Inspect valve guide bores using a dial bore gauge and repair where needed.
? New OEM German Phosphorous Bronze Valve Guides & Valve Stem Seals are installed
? All valve seats are cut, not ground, using three angle cuts for maximum precision.
? The valves are inspected for stem and valve face damage and/or wear, as well as straightness.
? All valves are hand ground and/or replaced as needed.
? Thoroughly inspect and test all of the valve springs for proper tension / resistance and replaced as needed.
? All head surfaces are machined (milled), not ground!
Final cleaning and assembly includes; Cleaning all heads in a solvent base tank in which all oil galleries, thread holes, etc. are cleaned. A number of different brushes are used to catch any remaining contaminants. All heads are run through a detergent based hot tank before assembly. All assembly work is done by hand by Professional and Expert Porsche Specialists.
Using only Genuine German (OEM) Gaskets, the engine is reassembled to factory specs.
