rebuilt engine break in oil

3.2l rebuilt - what type of oil should be used for the initial start up of a rebuilt 986 engine.
Then after the first 20 milles or so, what type of oil should I change to for the next 1000miles?

Are the rings or cylinder finish new?

Talk to Jake Rabe:

Use the Joe Gibbs break in oil. I don't remember the code name. Then run the Joe Gibbs DT40 5W40. You can find the break-in oil on Jake's site or L&N Engineering's.

Flavour 987S thanks.

By Pro, the rings are new (porsche) the cylinders were good but they were just lightly buffed (lokasil) to help seat the rings. Stock pistons and rods. Stock cams and tappits. Stock valves.

new triple row LN IMS, 3 new chains, new chain guides, I can't remember all the other news right off.

Start with the JG BR-30 & run it about 300 miles. Start out in stop & go traffic trying to get the temp up to 180+ constantly varying rpm without exceeding 3500 rpm.

By Pro, is there a second choice to Joe Gibbs. I'm not sure I can find Joe Gibbs up here in New Brunswick. I called 3 different Auto Supply stores and no luck but I'll try the engine rebuild shop tomorrow, maybe they can order it in.

What about after I drain this initial stage oil off, I still have to use conventional type oil for the next 1000 miles don't I? What weight?
The Dt 40 (5w40) is synthetic?

You can order the oil from L&N or Flat 6 Innovations' web sites. About $150/case of 12 bottles.

Yes, the Joe Gibbs DT40 5W40 is a full sythetic oil. High in Zinc and Phosphorus.

Send Jake or Charles (L&N) an email or PM with your other questions.

It may be hard to seat the rings, you should consult whoever honed the cylinders.

George Navarro. from LN suggested 2 oils to break in the motor they machined for me. Brad Penn BR-30 and the before mentioned Joe Gibb BR oil.

After which use the Joe Gibb DT40, Brad Pen 5-40 full synthetic or Motul

The regimen that I developed for our engines is as follows:

Joe Gibbs BR 30 or 50 based upon the internal clearances of the specific engine and ambient temperatures during the break in process. Lake Speed from Gibbs and I have developed a BR40 that we are testing now, specifically designed for our engines.

I will run BR for all of our dyno work and during my 200 mile evaluation of the engine. We then carry out an exhaustive, invasive inspection with the sump plate pulled, compression and leak down tests, borescope inspection of the cylinders, and we draw an oil sample for base line.

We then swap to another proprietary Gibbs product which is an "intermediate oil" thats a 40 wt, high zinc conventional oil that is ran for the first 2,500 miles that the owner drives the car after receiving it from us. With Nickies we have learned that this intermediate oil is critical to reducing oil consumption before going to a synthetic oil. We instruct the owner to draw a sample of this oil and send to us so we can gather more trend data. (This product may become a Gibbs product, like DT40, DT50 and XP9 have after our development)

We then swap to Joe Gibbs DT40 and shorten the first service interval to 2,500 miles. After that, depending on wear metals and viscosity and the condition of the anti wear package in the used oil analysis we can begin the 6 month/ 5,000 mile service intervals that the engine will have for the rest of its life. Watching the anti-wear package levels is a great way to see if the engine is thoroughly broken in and ready for service with no other special attention.

We only use the Gibbs products, because we have worked closely with Lake Speed to develop them, that includes only using Gibbs assembly lube. This is how we level the playing field to ensure that our oil analysis truly shows the condition of the engine break in.

This is what I do... It doesn't mean that its the only way to do this, it is overkill to many, but its one way that we maintain our reputation and its why we have only had ONE warranty repair in the history of of our engine program. Few people develop their own components; even fewer develop their own engine oil. The funny part is our competitors love the oil and that means everything they create has that much more Raby influence! Thats the part they hate :-)

Just to help you out a little. It is CHARLES Navarro (great guy). And I don't think the Brad Penn products are full synthetics, they are partial blends.

Great information guys, thanks.
I just got back from the engine shop and he does carry Joe Gibbs and Royal Purple so I now have a supplier of Joe Gibbs.
Because there is not a conventional 40 wt Joe Gibb oil, he suggested for the second stage of break in to use a conventional vavoline or castrol 5w40 with a zinc additive from a GM dealership. So it sounds like he's on the same wave length as Jake and Charles.

What about changing transmission oil.
Other than Porsche what is the next recommended brand? I was told by a Porsche dealer to use a synthetic 75W90. Anything wrong with Joe Gibbs or Royal Purple?

Thank you. Did not know this. Brother, father, uncle? I'll have to ask him at Road America Labor Day weekend.

Buy the Porsche 75W90 synthetic gear lube from Sunset Porsche. Cost about $25/quart. You need 3.

I've bought a fair bit of parts and supplies from Sunset for this project, they've been very good.
BUT they won't ship liquids, they're not the only ones. Even the Porsche dealer here in eastern canada won't ship liquids, its a liability issue I've been told. So unless I drive and pick it up I can't use Porsche transmission oil. The local porsche dealer (4hrs) brings it in by the barrel, no gallons or litres, so I can't buy it there.

^Thanks, Jake! So now I know where Charles gets his greatness. Parenting is such an important tasks, and not easily done.

Thanks your for the apology, Just to help you out a little.
Brad Penn is producing at least 3 blends of full synthetic oil. Pricing locally from Wrench-Rite (they are a performance Truck/ 4WDR shop) was $7.95 a qt. The 5W-40 Joe Gibs DT40 is now $121 per case.
Available blends are marketed for high percentage ethanol fuels up to 15% ethanol
Brad Penn FSFG Full Synthetic SAE 5W-30
Brad Penn FSFG Full synthetic SAE 5W-40
Blower oil blend Brad Penn FSFG Full Synthetic SAE 75W 90
They started marketing these in May 2012
You are probably right that LN was endorsing their partial Synthec oils.
