Rebuilder's Valves

The patented Enginetech “Rebuilder’s Valve®” is designed to open up that bottle neck in your cylinder head department.  For about the same cost of reclaiming valves, you can install brand new Rebuilder Valves®.

Rebuilder valves reduce seat, guide, spring, and spring shim replacements. 

Rebuilders Valves Reduce Seat Replacements:

The head diameter of Enginetech’s Rebuilder valve is 0.010″ to 0.030″ oversized, allowing extra seat machining which means fewer seat replacements. The stem diameters are 0.008″ to 0.015″ oversized allowing you to simply ream the worn guide in on step. Enginetech makes the valve fit the reamer to where only one reamer is needed to get the correct oil clearance on both intake and exhaust valves. We have also lowered the keeper groove 0.020″ to 0.030″ towards the valve head. Spring pressure is automatically boosted by the lowered keeper, eliminating the need for spring shims while still allowing for new springs to be used where necessary.

Eliminate Guide Replacements:

The Rebuilder’s Valve® stem diameters are oversized 0.008” to 0.0015”, depending on the application.  Only one valve guide reamer is required per engine.  This is because, unlike the competitor’s valves, Enginetech makes the valve fit the reamer rather than making the reamer fit the valve.  With only one reamer, you get the correct oil clearance on both intake and exhaust valves.  No guide replacement or liner installation is required.  Simply ream the worn guide in one step and you’re done.

Rebuilders Valves Claim More Springs & Eliminate Spring Shims:

Valve springs weaken over time.  In the past, rebuilders would install shims with reclaimed springs to boost valve seat pressure back to normal.  The Rebuilder’s Valve® does this for you.  Enginetech has lowered the keeper groove 0.020” to 0.030” towards the valve head.  Spring pressure is automatically boosted by the lowered keeper, thus making spring shims obsolete.  New springs can also be used.

Rebuilders Valves Are Made With Superior Materials:

Enginetech Rebuilder’s Valves® are better than OE.  Enginetech knows that remanufactured engines are installed in very harsh environments.  Therefore, we have upgraded the materials of our Rebuilder’s Valves® for severe duty.

Our one piece intake valves are made from HNV-3 high alloy valve steel (often used for exhaust valves).  All of our valve stems are either triple chrome plated or gas nitrided.  We even go a step further and harden every valve tip to 50HRC minimum.

Enginetech’s exhaust valves are also a one piece design.  All Rebuilder’s exhaust valves are made from EV-8 or EV-12 stainless steel.  Again, like the intake valves, all stems are triple chrome plated or gas nitrided.  Wafer tips, hardened to 50RHc, are inertia welded to every tip.
