Is there a simple way to get a 914 jacked up enough to change oil Options

[dlindzey]

I can't even find a shop willing to change my oil so I am going to have to crawl around on the floor for a while. I have all the parts and a creeper but get confused on where you can put a floor jack and where you should put a jack stand as seems like same point is best for both the jack and the stands.
I have located the 4 donuts at the corners of the cab/chasis juncture, they seem ok. I am tempted to just get two floor jacks and jack up the rear at the donuts and call it a day. Is it dangerous to use jacks for support rather than putting a jack stand under there somewhere?
Ramps won't work as exhaust tip hits the ramp.
How do most of you solve this issue?

Those "donuts" are not designed to jack up your 914. They will bend/deform.

Use a jack plate inserted into the jack point Porsche designed for jacking up your 914.

Here is a diagram showing where you can place stands. Although it shows the "donuts" in the diagram, those are not good/safe locations for jacking up your 914. You decide where its safe and less prone to damage your 914.

When we don't jack up the 914 using the jacking point, we use a 4x4 (maybe it's 6x6?) piece of hardwood that goes almost the entire width of the car and is placed under the firewall when jacking up the rear and under the area behind the front cross member when jacking up the front. Since we use a 4 post lift and two tall stands, it is very quick. One stand on each side of the 4x4 and then lower the lift and lock the safety catches and we're ready to work.

Best wishes for a safe oil change.

One final comment. It is very very dangerous to have an incompetent shop/mechanic change the oil on a 914. If the bolt that fastens the strainer cover is tightened with too much torque, you can end up with "type iv syndrome ". This is where the internal part of your engine case breaks and pretty much destroys the engine. At a minimum it's a very expensive repair.
