Datsun Roadster Silicon Bronze Valve Guides - Set of 8 or In 4 packs of Intake or Exhaust

R16 Silicon Bronze Valve Guides (8)

In photo Intake on top/exhaust below. Nissan guides were mediocre brass and standard on the OD not providing adequate press for re-installation. Proper guide press fit is essential in rebuilds. Losing a guide in older engines is more common depending on how many rebuilds have been performed. These guides are slightly oversize on the OD to provide the correct press fit.
The longer, tapering, angle toward the end of the guide is the intake guide.
To order the intake or exhaust guides separately in (sets of 4) use the following part numbering and pricing.

Datsun Roadster 1500 & 1600 Early & Late Roller Rocker Arm Assembly

Roller rocker arm assemblies were originally developed for the Datsun roadster in the mid to late 1980's into the 90's by Datsun engine guru Dave Weber, now deceased, at Malvern racing. They were manufactured and developed by JB racing in Florida and were offered in different rocker arm ratios. The ones supplied here were not the first roller rockers available in the world, but are of the highest quality available.

These fully assembled roller rocker arm assemblies first appeared in the late 90's. "Aluminum, machined not extruded, 2024 cold finish LH and RH roller rocker arms. Rocker arms are bushed with 660 bronze bushings and are assembled onto a ground and hard chrome plated shaft. Ratio is 1.5 at the valve with a valve lash of .014 to .016. Easy Allen key adjustment for valve lash on twelve point locking nuts".

Datsun Roadster Valve Stem Seal - (Set Of 8) OEM TO NISSAN

NOTE:63 - 65 1500 & 65 - Early 67 1600 cylinder heads can be modified to accept these better seals. Early o-ring seals are not only out of production, but they do not control oil from dripping down the guide resulting in excessive oil consumption and carbon build up on the valves.
To convert these cylinder heads the cylinder head must be removed from the vehicle. Remove the valves and have your machinist remove the small step that sits underneath the inner valve spring. This will allow this later style valve seal to work.

Datsun Roadster Smog Plug Inserts - Set of 4

Datsun Roadster, set of four, smog plug inserts for 68 -70 1600 and 2000 cylinder heads.

These inserts were reverse engineered to screw into the ports in the head where the air injectors were installed as smog equipment. They have the exact thread and contour of the injectors and fill the entire cavity; both the threaded portion and the smooth bore. This completely eliminates that annoying “chirping” sound caused by engine exhaust passing over the tube, which creates a resonant chamber (like a badly played flute).GENERIC ALLEN HEAD SHORT PLUGS WITH NO EXTENSION WILL NOT SOLVE THE CHIRPING ISSUE. SHORT PLUGS ARE $1.00 EACH AT YOUR LOCAL PLUMBING SUPPLY
Once installed, you’ll be amazed at hearing only the smooth hum of the exhaust out the tailpipe. The clucking chicken in your engine will be dead and gone! Does not include clucking chicken. Comes with a full detailed instruction sheet.
NOTE: Another option is not Allen plugs Allen plugs do not have a chamfer to meet the angled machined area at the bottom of the casted hole in the cylinder head nor do they have an extension on the end to close off the smaller id hole where the pipe used to fit. These areas are what cause the chirping noise. Our inserts have these necessary additions. They were designed, blueprinted and manufactured for a specific purpose.

NOTE 1st PHOTO: The 1st part in the row is the original exhaust injector. It is in the photo group to show what is in your car that you will be removing and is for reference only.

Datsun Roadster 65 - 70 Thicker R16 1600 Head Gasket .120

No longer necessary to use a all copper head gasket and the different challenges in making it work. Also not necessary to double stack two stock gaskets and pray for this method to stay sealed.

1ST photo. Stock thickness gasket on the left. New thicker gasket on the right.This all new gasket is .120 thick compared to the Nissan stock gasket which measures .053 at the fire ring.

Why buy a thicker head gasket? During a R16 cylinder heads life span it can be surfaced many times to the point where the head is nearly unusable. If your head has been overheated and warped it requires either oven straitening, expensive, or a re-surfacing of both sides of the head in order for it to be flat again. Thinner cylinder head castings have a serious problem of diminished chamber volume resulting in higher compression and detonation. If you are using dome pistons mechanical interference with the valve pocket will lead to either small end or big end rod bearing failure. The valve pocket can be professionally and carefully machined, at an additional cost, so as to provide mechanical clearance for the pistons, but this does correct the problem of subsequent and undesirable higher compression.This new gasket gives you the opportunity to correct the issue of a overly planed cylinder head by lowering the compression and by providing adequate clearance between the pistons and the valve pocket. Includes a instruction sheet.

We recommend that you purchase a tube of the special silicone we sell part#2402 help seal the rear oil gallery of the cylinder head gasket

Gasket construction and properties: High performance, high density composite, graphite facing, much like a Felpro gasket, on a perforated carbon steel core. Stainless steel fire rings installed at each bore. Graphite has excellent sealing, conform ability and high temperature resistance.

NOTE: It is highly recommended that you use our R16 performance head stud kit when installing this gasket as it is superior to the original head bolt design.
