i worked on the first sierras back in 1982, a well dressed cortina,i thought at the time, now the datsun stanza, was away ahead of their time, like the wee daihatsu charade, of the early 1980s.
Hi, i took the head off my car because the timing belt snapped and belt all the valves. Its a renault petrol (clio 1.2 16valves petrol) i replaced all bent valves, grinded in and re assembled the camshaft and rockers, this is my question? Should the camshaft feel quite tight to turn over by hand by placing a ratchet & socket on the camshaft sprocket? Even with my rockers fully unscrewed out of adjustment (ie backed off completely) its really tight to turn over and the head is off the car!, should it be tight like this, is this normal? I have yet to adjust the valve clearances yet, but stopped because i panicked over the tightness, i thought it should be quite easy to turn. It actually turns, i feel resistance then it jolts forward when its coming off the top of the lobe, it does this 4 times for every revolution of the camshaft sprocket, its a 16 valve Please advise if its normal to feel quite a bit of resistance with no belt on and head off vehicle
Would it be possible to turn the camshaft over with your hand by holding the sprocket?, should it have more resistance than that, i cannot turn mine over by hand without using a socket or spanner, is that still the normal resistance if you cant turn it over by hand
i have same D7F720, problem is compression 2-3 cyl same 60 psi. 1-2 150psi. Suddenly. What is the problem? car works 2 cyl. spark is there, als fuel. I never adjusted valves. I just read they are not hydraulic.
Hello. I have a D4F 728 engine. I bought a Erling gasket and screws. 258.270 The screws are tightened with a torque of 20Nm + 230 degrees. Erling recommends 20Nm + 115 degrees + 115 degrees. I tightened 20Nm + 90 degrees + 90 degrees + 50 degrees. This method eliminates head tension when tightening the head screws, and minimizes the risk of distortion of the gasket under the head. I apologize for the mistakes, I used the google translator. Witam. Ja mam silnik D4F 728. Ja kupiłem uszczelkę i śruby firmy Erling. 258.270 Śruby dokręca się momentem 20Nm + 230 stopni. Erling zaleca 20Nm + 115 stopni + 115 stopni. Ja dokręcałem 20Nm + 90 stopni + 90 stopni + 50 stopni. Taka metoda niweluje naprężenia głowicy przy dokręcaniu śrub głowicy, oraz minimalizuje ryzyko zniekształcenia uszczelki pod głowicą. Przepraszam za błędy, korzystałem z tłumacza google.
