Are you finally buying your dream car, “God’s Chariot”? Here are two important DIY’s that you’ll need to learn when you buy your E30 3 series BMW. First, the valves on an M20 6-cylinder engine will need to be adjusted roughly once a year or every 15,000 miles. This keeps your car running correctly and reduces the possibility of breaking a rocker arm. Poorly adjusted valves can put additional stress on the already fragile rocker arms in this motor, so be sure to stay on top of this maintenance item. Adjustment of the valves on an M20 engine requires simple tools: 10mm deep socket and ratchet with extension Stainless steel feeler gauge set to measure the correct gap Alan key set; use a small key to adjust the rocker eccentric while adjusting New M20 valve cover gasket This procedure should take you anywhere from 1-2 hours depending on your experience and mechanical aptitude. Perform this check and adjustment in early spring each year when taking the car out of storage, before the driving season begins. …
Hello internet friends and E30 community! I am putting all of my E30 M3 parts up for sale this weekend and this post will serve as a preview of the parts I’m clearing out. As you can imagine, this collection has taken many years to get together and was initially intended for an E30 M3 conversion on a standard E30 body. I’m focusing my efforts on collecting more interesting things now, like digital Pokemon.
Hartge was a third party tuning company founded in Germany in the early 1970’s. They modified new BMW models for customers, much like Alpina, Racing Dynamics and AC Schnitzer. One of the earliest Hartge models was the H23 based on the euro 323i which was produced from 1983 to 1985 in Germany. They modified the engine with custom forged pistons that yielded a high compression ratio of 10:1 along with a new camshaft, exhaust and chip tuning. To top off all of the engine work, it was finished with a custom cast valve cover. Very few Hartge and Alpina cars were produced, and as a result the vintage tuning parts are now very sought after.
Learning how to correctly adjust the valves on your M20 engine is an essential part of E30 ownership. Howling sewing machine sounds are to the E30 as air cooled flat six sounds are to the Porsche 911. Just how much sewing machine you get is up to you and your valve adjusting skills.
