Hello all,
I have a 92' 300SE which I just replaced the head gasket. Trying to get the cams aligned correctlly. I have the exhaust cam where it should be but when I tried to dial in the intake cam from the crankshaft the valves seem to be hitting the piston. So I then tried to dial in the intake cam by turning the camshaft but for some reason it dosn't look right. Can an expert provide me with some information of where I should go from here.
Here is the process I am following:
Adjusting Camshaft Basic Position :
Proceeding work
Basic position of camshaft checked. Refer to
Camshaft, Engine - Testing and Inspection - Procedures
Adjusting
- Position crankshaft to 30°BTDC of cylinder 1 (arrow).
NOTE: At 30°BTDC of cylinder 1 the camshafts can be rotated without the valves touching the piston crowns.
- Remove chain tensioner (5). Refer to
- Remove front cover (30) and top guide rail (42).
- Unbolt exhaust camshaft sprocket (3).
- Rotate camshafts with wrench (25) 119 589 00 01 00 (WAF 27) or 104 SB9 01 01 00 (WAF 29) until the 4 mm holes in the camshaft flanges are touching top edge of cylinder head.
- Insert pins (1) into holes (arrows).
- Rotate crankshaft with wrench socket insert in direction of rotation of engine to TDC position of cylinder 1; raise timing chain for this step.
- Rotate camshaft adjuster by hand in direction Of rotation of camshaft to "retarded" position stop.
- Fit timing chain onto inlet camshaft sprocket and check whether timing chain is resting correctly against guide rail in timing case cover.
- Install exhaust camshaft sprocket (3) in base position of camshaft.
- Install front cover (30) and top guide rail (42).
- Install chain tensioner (5).
- Check basic position of camshafts.
Thanks in advance!!!
