Glow plug removal aid.

Mercedes switched over to the Bosch pencil style glow plugs starting with the 601 motor in 1987 and used all the way until the latest inline diesel Sprinter. These glow plugs are a cylinder head engineers dream with their long and slender compact design but an absolute nightmare to the repair shop tasked with having to replace them. These glow plugs have been known to seize and break upon removal and there are four main reasons this happens all resulting in a very expensive repair bill (Bearing Service in portland charges 300 per broken plug after pulling the head and it being on the bench).

The four reasons the glow plugs will seize and break off in the head have been narrowed down to the threads seizing from corrosion, this will break the glow off without ever turning when attempting to loosen. The long shaft being impacted with carbon, usually resulting in getting 1 to 3 turns before it starts to bind up, creak and groan. The tip being coated in carbon usually is in the 3 to 5 turn range before it binds up, less creaking and groaning with this do to the surface area. Then the last reason for seizing is the tip of the glow plug overheating and being egg shaped, when this happens you are stuck either with most of the threads out or completely out.

The goal of the service is to reduce the chance of breakage where the carbon is to blame. The diesel care and 244 ran through prior to service will usually remove or at least soften the carbon you would be fighting. I personally have been involved in multiple services doing it this way and there has not been one that couldn't be removed(some needed a bit of love'n to get it but no machine shop work).

Audi 2.0 FSI oil consumption

Currently Audi is having an oil consumption situation with their 2.0 Fsi motors. There was a piston ring update mid 2006 that resolves an issue with the piston rings losing temper and no longer having outward pressure against the cylinders. Now they are trying different pistons even though it appears that the issue is a build up of oil deposits in the piston ring lands and the oil control ring holes. Audi has also implemented a current service action on the crankcase vent valve and the turbo pipe has been revised. These motors would benefit greatly from a BG 109 oil flush to soften and disperse the oil deposits then follow up with MOA to keep the deposits from building up again. If done every 5k miles the engine would qualify for a lifetime protection plan. These pistons only have 26k miles on them and if the customer was current and on time for all services they would have just received the 3rd oil change. It's possible that deposits could be build up like this after just 2 oil changes.

VW TDI

The VW TDI motors have a reputation for plugging up the intake manifolds with carbon deposits. These deposits can build up in the course of 20k miles or so and some can build up sooner. Most of the time when the vehicle makes it into a shop with the lack of power as a concern the intake is so plugged the only option is to pull the intake off and clean it out. If checked at service intervals and monitored a shop has a chance to do a maintenance repair without the removal of the intake. This will result in a more efficient engine, improved fuel economy and reduced maintenance costs which will benefit the customer. I currently have access to the very limited tools VW had BG design and manufacture for doing the maintenance service, very graciously loaned by a local shop. Regular oil changes with DOC can reduce the amount of crankcase vapors in the intake manifold reacting with the EGR gases forming the deposits.


Note this tool set also has the EGR cooler cleaner adapter with 6 psi regulator. This tool set is available for purchase from a local shop, contact for their contact info.




If this would have been caught in time it could have received a maintenance service instead of the repair procedure that was performed.

ZX6R Injection Service.


Carbon Build up, upper injector screen restrictions and injector pintle deposits had developed on a 2008 ZX6R that Ron at RPM had at his shop. We worked together and came up with a procedure that we both thought would alleviate the issue this bike had developed in the first 5,000 miles of operation. Utilizing the VIA tooling with the 210 injection cleaner we hooked up directly to the fuel rail with the tank and fuel pump removed from the bike. We did have the benefit of his dyno for monitoring the bike while the service was being performed. The results were impressive with a 5% power increase and an improved A/F ratio. The reason for such an increase has a lot to do with motorcycles operating open loop fuel injection and cannot correct fuel trim issues like a closed loop automotive injection system utilizing an 02 sensor. Any restriction or deposit formation will effect preset A/F trims at the factory. Even though the run time was a little longer then ideal and we have a few adjustments to the service procedure for next time we were still pleased with the results.  I'll upload the dyno charts when I receive the files. RPM will be the only motorcycle repair facility in the area with the tools, chemicals and more importantly the know how to perform the service.

2007 Tundra Transmission service.

2007 Tundra transmission service.

A friends Tundra was due for a transmission service and he wanted to do everything possible to insure he would get the most life possible out of it. This led to deciding to use a Gen 1 PF5 with 16 quarts of 312 universal synthetic ATF and a 6600 transmission service kit (106 Quick Clean and 310 ATC+). The 312 is suitable replacement for Toyota WS fluid. The used fluid was far darker than expected but cleaned up nice. When doing this service make sure the transmission thermostat is in the bypass position to ensure full fluid flow. This Tundra also has been known to haul some of my favorite motorcycles around so there was a vested interest on my part also.

Dynamic Engine Cleaner

Dynamic Engine Cleaner

A client had a heavily sludge BMW 3-series and needed to find a cleaning solution or motor replacement. The Dynamic Engine Cleaner was used while carefully monitoring engine vitals at all times. I'd call it a success in just a half-hour run time.

Just plain sexy!
