Figure 1 In order to remove the engine cover s yellow arrows , you first have to remove the cabin microfilter housing green arrow. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements. Follow the instructions that came along with your special tool kit to ensure proper use. Can I replace it myself? Stage 3, use an angle finder and tighten the head bolts an additional 90°. This connection is very important.
Before repairing a faulty head gasket, attempt to re-torque the cylinder head bolts. If there are no external leaks but it doesn't hold pressure the head gasket may be faulty. Drain the engine oil and coolant. Install the new cylinder head bolts into the cylinder head. Our vehicle may vary slightly from yours as models do change and evolve as they grow older.
For warranty evaluation please create a support ticket via this form. Thanks for your recommendations and encouragement! Recycle parts, packaging and fluids when possible. Though one bit that we wanted to upgraded was our valves. Warranty claims will not be honored if the product was not purchased through an approved dealer. Guess I'll have some time to do that this summer because it's too close to my seasonal migration north to start such an ambitious project now.
Install the engine-hoisting hook and tighten. These engines need to be treated like a sports car engine and not like a Honda Civic. Next, remove the camshaft and crankshaft locking tools. Remove the spark plugs and inspect each cylinder for signs of coolant. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material Viton designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. If the coil resists, twist when pulling up to break it free from the spark plug.
The cabin microfilter housing remains the same throughout all years. Pelican Parts is not associated with Porsche Cars North America in any manner, except for a mutual appreciation and love of the cars.

Coolant is getting low and my oil has coolant in it.
June 18, 2017 Followup from the Pelican Staff: Each manufacturer of sockets will vary. Calculate the required thickness of the thicker head gasket based on the desired new compression ratio. Torque the head bolts to specifications, which may change with the new thicker gasket. Install the engine cooling fan and shroud. We step torqued the mains up to a final value of 60 ft-lbs.
Be sure to have your cylinder head professionally cleaned and pressure tested before reinstalling. I pulled a valve cover and located the casting number and date code on my 402 heads today. Since we are running our E46 on only 9 psi of boost, we wanted to minimize the torque loss from a lower compression ratio piston. The cut rings will sit right inside of the head gasket, with no machining or o ringing required. September 3, 2016 Followup from the Pelican Staff: I answer tech questions.
Each cut ring features three sharp grooves to cut into the cylinder head and crush between the head and block. You can access it from below the vehicle. Your 402 may be just. They just push back into place. Open chambers typically have a larger combustion area than closed chambers, and they tend to breath better on the street. Thanks for pointing this out.
