Posted: Thu Nov 15, 2018 14:15 Post subject: Very clattery after head swap. Timing? |
|
|
(L400 2.8 TD 1997 series 1)
Just replaced head and gasket. Suspected blown gasket, turned out to head cracked between valve and precombustion chamber.
Initial startup okay, after a few min of idle was chuffing. Took the manifolds off and found two smoking guns, both my fault. Miss aligned inlet gasket and half of one of the exhaust gaskets was missing. Fixed both.
Second start up, idle okay. As soon as I tried to drive, relay loud clattering, like diesel knock of old. Yes it's barely above freezing. But could I have screwed up the timing one tooth of the chain? would this cause the problem?
Should I just idle till warm? Should I take the rocker cover off/ wire down a glow plug and check vs timing mark on the pulley - I did this on reassembly and thought all was okay.
Compression could of course be higher with new head?
Just never owned anything that clattered this much on startup (Citroen BX 19D, Disco 200TDI, VW T4 1.9 TD and 2.5TDI even Bongo 2.5TD)
I have heard worse from vehicles of non loving owners, especially transits of old. |

When its running crack off, then retighten each injector pipe at the injector end. _________________ Artificial intelligence is no match for natural stupidity.... |

Idris.
The marks on the pulley (crankshaft) may be reliable due to possible de-lamination of the rubber twixt the two parts.

Unreliable, even.
The late and great V8Rick timed mine via the notch in the front of the cam and a piece of net curtain wire down heater plug one, he could feed this through the pre-ignition chamber and then feel the movement of the piston. _________________ Artificial intelligence is no match for natural stupidity.... |

This was the answer, although I solved it by driving gently uphill for 10 min, got it good and warm, problem evaporated.
As for the pulley not being a reliable source of TDC, it was the relationship of the pulley and the camshaft I needed, nothing to do with inj pump. So it would be pulley or possibly flywheel/flexplate? |
