Introduction
The following is a list of sealants used on Porsche 924s, 944, and 968 and their applications. You can probably find a number of acceptable aftermarket replacements. However, these are the ones that are “approved” for use by Porsche.
| Sealants | ||
| Part Number | Description | Applications |
| 043 010 00 | Loctite 574 | Engine Block halves, Oil Pump housing, Balance Shaft covers, Oil Dipstick guide tube, Balance Shaft sprocket retaining bolts |
| 043 011 00 | Loctite 638 | Originally intended for use on Balance Shaft covers and is still listed in some older copies of the factory shop manuals. However, has been replaced by Loctite 574. |
| 000 043 019 01 | Silastic 730 RTV / Dow Corning 730 | Both sides of the corners of the oil pan gasket. Brutally expensive. I have used Permatex Ultra Grey instead with good success. |
| N/A | Dow Corning 111 | Not specifically recommended by Porsche. However, it’s a good idea to lubricate all o-rings and seals on installation to improve their sealing properties and to allow them to move as they expand and contract. |
| N/A | Loctite 270 | Oil pan insert bolts (M5), Water Pump to Crankcase bolts (M6), Reference Mark Sensor stud on flywheel |
| N/A | Loctite 221 | Rotor to camshaft connector retaining screw (M4), Camshaft connector to Camshaft Sprocket Dog retaining screw (M5) |
| N/A | Loctite 262 | Main Oil Duct end plugs sealing surfaces |
