Blown Engine

Did they tell you what caused the old engine to fail?

How much was the replacement work? I think prices are on the invoice.

The old engine developed a hole in one of the valve lifters. I think the cost of the repair was about $10K.

Randijo, make sure you properly break-in the new engine. I would also change the oil at about 1,000 miles.

Why does the oil need to be changed at 1000 miles?

We generally follow the maintenance schedule from Porsche which for our year says to change the oil at 2 years or 20,000 miles. Are we making a mistake?

Do you own or lease? If you own, I would change the oil at 1,000 miles. Just my opinion. Worth the $150.

If you liked the engine changing experience, just change oil every 20,000 miles. You should change the oil between 7-10K miles or at least once per year prior to winter storage.

Did you follow proper engine break-in with your first motor?

No lease. We own it.
We followed proper break in procedure on the first engine and we are braking in the new one the same way. We keep the RPMs under 4000, no full throttle starts, and try to vary the speed for the first 2000 miles.
The old engine only had 12000 miles on it after a year and a half. According to the maintenance schedule it wasn't yet due for an oil change. Do you really think changing the oil once a year will prevent engine failure?

It wouldnt hurt to do it.

Randijo, good job on doing the proper engine break-in. Not an easy thing to do. Requires great patience! Must be even harder with the second engine, partly because you know what the car is capable of doing, and are more accomplished at driving it.

You should have changed the oil prior to last winter's storage. Did this cause your engine failure? I doubt it.

Let say you are going to keep the car 10 years. And you change the oil yearly. Will this "prevent engine failure"? In a nut-shell...yes. Could something else be the cause (IMS)...sure. If you changed the oil once in 10 years...would the engine fail...my money says yes. What if you change twice? How about 3 times? What is the level of risk you are comfortable with?

Changing oil is cheap insurance. Even cheaper for the many great DIY'ers on this Forum.

Don't forget, Randijo, the oil in our cars does about 40% lubrication and 60% cooling.
