Loud noise from 2.25 petrol engine (video with sound)
Hi. First of all, sorry for any bad spelling. English is not my native language.
I'm a new owner of a Land Rover Series III 109 from 1977 with 2.25 petrol. Have never owned a Land Rover before so my knowledge of these cars is limited.
Has a really unpleasant sound from the engine during cold starts, watch the video link and listen carefully. The noise occurred some day after I did an oil service and with new ignition parts. The sound comes from the front of the engine and is prominent during cold starts and when increasing the RPM of the engine. The engine seems to be very difficult to get really hot but when it finally gets hot-ish the sound disappears. If I drive with the heat on in the car, however, the sound returns even with the "hot" engine.
Video link!
Info:
The oil is newly changed, Kroon Classic 20W-50
New oil filter, new ignition cables, spark plug, battery, distributor cover, breaker points, ignition coil and belt.
The ignition is set to approx. 3° BTDC and I can not set it earlier because the vacuum diaphragm on the distributor hits a screw head on the cylinder head. See photos.
Ignition is measured with ignition strobe light, 800RPM idle and without vacuum connected to the carburettor.
95-octane gasoline.
14.1 V voltage across the battery (wondered if the sound could be from the belt sliding on the alternator pulley)
Follow-up questions:
1. How hot should this engine be? I can put my hand on the radiator cap quite immediately after being out and driving approx. half an hour. Is it too cold?
2. Regarding the distributor and the vacuum advance diaphragm hitting the bolt head, can i turn the distributor 90° counter clockwise and then move all the ignition cables one step clockwise, so I get more room to fine-tune the ignition?
