Oil leaks are not a normal characteristic and if you are servicing a vehicle and leakage is present, it should be brought to the attention of the vehicle owner and documented on the repair order for future reference. Keep a copy just in case of engine damage that may occur later, especially if the repairs […]

1985 Article about the BMW 635csi

In many ways, the 635CSi is a superlative car. It produces prodigious speed thanks to its new 3.5-liter engine. The 635csi exhibits much better handling than BMW’s early 6-series coupes. It is put together ,vith rare care. Its ergonomics are generally excellent. And now it has Bosch ABS anti-lock braking equipment for help during emergency stops. All told, the 635CSi is a very accomplished piece of work.

Still, we’re talking 3.5-liter, high-rev­ving. seven-league boots here. BMW has punched out the 3.2-liter bore from 89 to 92mm, and the torque has increased from 195 to 214 pounds-feet. This single overhead-cam six is old. but it remains atop the pack in basic design. Its aluminum hen1i head is fed by Bosch Motronic fuel injection. Crossflow intake and exhaust ports handle the breathing. and a new, adaptive Lambda-sensor control sets the fuel-air mixture more precisely through a ,vider range of operation. ·ro allow maximum spark advance at all times, BMW has not yet resorted to a knock sensor, and the 3.5-liter motor compression ratio remains a impressive 10:1. The added dis­placement has bumped up, the horsepower only from 181 to well over 250hp. However, it is tuned instead for midrange response, the big six’s power peaks at 5400 rpm, 600 rpm earlier than in the 3.2-liter. A 3.45:1 final-drive replaces the 633’s taller 3.25 gear, boosting the throttle response throughout the rpm range. but a rev limiter clips the power smartly at 6200 rpm.

We had to make a custom adapter for a T4 Eurovan Coolant Bottle Bracket Adapter the other day. We needed a new coolant reservoir for our customer’s 2001 Volkswagen Eurovan VR6 MV. The warehouse sent me the wrong reservoir (Ver C, and not a Ver E). (701 121 407 E) Apparently these coolant reservoirs are no longer available and almost impossible to find.

Instead of wasting time trying to find a new one, we drafted a file in Fusion 360. Then we 3d printed this bracket. Printed with ePA-CF Carbon Fiber (25%CF/75%Nylon). The bracket is safe up to 220c / 428ºF. This will adapts the older C style bottles with the overflow on the right passenger side (that are readily available) to the left side drivers hose configuration for the Ver E bottles. 2001+ T4.5 – 24v Engines. We also installed some brass inserts so we can just bolt it right in and it can be replaced it in the future if need be.
