My new lifters and new cam need preload setting. I didn't change the pushrods , they are ok. I compare the new OEM with the original , it s quite the same (photos) except the size of the cup that hold the pushrod inside, it's larger and deeper. I wonder if i can put the original "cup" on the new...

I v'e just put my new lifters and cam and keep the old pushrods that are in good shape. I notice the top of the new lifters is a little larger and deeper than the old one , about 1 mm, and my composite head gasket is thicker than the tin one. The result should be not enough preload for my...

HI, I 've just put back my Heads (with spark plugs) with a new gasket (Elring composite). When i turn the crank , I need 40 NM torque and even more after first move, and i can hear compressed air coming out almost at the rear of the heads ... Is it normal ? Valves leaks ? video here...

Hi, after surfacing my heads (to clean the old gasket marks) i found these measures : 23,30 mm (+ 0,1mm / 0,5 mm max. skimming ) 62,80 mm ( + 0,2 mm / 0,5 mm max skimming) Should i put a thiker composite gasket instead a metal one ? the gap can be fill with shim on rockers ?

the old seal has left marks...do i need to remove all before setting new gasket ? I use sand paper on a glass to remove these marks but i dont want to remove too much material; Is that enough like this ? Plus, I notice i remove more on the sides than in the middle , the head is not perfectly...

Hi , new post for my RRC EFI 3,9 with the good title ;) I have a question and a concern about a vertical mark on one of my cylinders, it is not a scratch, it is extra thick, as if a weld had been made. My compressions are correct (12,5 bars) and the engine is not knocking. Any idea what it...

J'ai 3 ou 4 clapets d'admission avec une légère corrosion (pas de trou) qui devrait disparaître avec le travail à la pâte. Je me demande si je dois conserver les originaux ou les remplacer par des neufs de rechange ? thanks

Hi, Made the mistake to mix the bolts. I will be very grateful if someone keep the assembly plan...

Hi, Remove the old seal...looks quite good. Any more i put a new one but not seems to be perfectly "watertight". Finally, I decided to put side to side the 2 seals, in case the new one is not 100% good . Any suggestions ?

The engine was not noisy or tapping bu i prefer to clean an inspect the 2 rockers shaft that seems to be original (130 000 miles). I wonder if i can grind gently (sans paper 1000) the arm and the rockers...

HI, My cam is removed : some lobes are really pitted and more...only few miles ahead...bad aftermarket one ! I will change my lifters too...for a better quality (turner engeneering OEM cam) I just surprised to see a sort of spacer (last pictures) , the fisrt cam bearing, partially cut and not in...

HI, I need to replace my camshaft (Range EFI 3,9) and i ask if i should change my genuine waterpump ( 130 000 miles, no leaks ) or replace it with a aftermarket one (genuine are too expensive ) ? Thanks.

HI everyone, Before insisting like crazy and doing something stupid, I would like to have an informed opinion on the direction of loosening the 32 mm fan nut. I read everything and its opposite: no screws on the left, on the right, unscrew in the direction of rotation of the fan, in the opposite...

Hello everyone, After cleaning my pistons, which were slightly charred, I was able to take a closer look at the liners. These are for some scratched (barely perceptible with fingernails) and also with black traces of which I do not know the origin. Can this affect the proper functioning of the...

My heads are off. I just discovered my rangie has no seal on exhaust valve, and just a flat black rubber disc on intake valve. Question, should I upgrade to neoprene fully enclosed seals on all 16 valve guides ?

Good morning, following my disassembly for my range with lower engine redone 12 years ago (very little driven since) but which notably lacked power, I took the compressions on my right cylinder head, 12 to 12.5 bars which is rather fine, except on the 1st where I couldn't take any compression...

Bonjour, J'ai juste démonté la rampe d'injection pour vérifier mes injecteurs (suspect d'une fuite). J'en ai profité pour démonter le collecteur d'admission, le joint de collecteur est très rouillé donc j'hésite à le remplacer. La rouille peut être due à une fuite dans le thermostat. J'espère...

Bonjour à tous, Mon silencieux arrière est complètement rouillé, à tel point qu'il dégage une fumée orange ...le problème c'est qu'il est très difficile de trouver le modèle de silencieux pour gamme non catalysé. Ma question est donc la suivante : est-il jouable de monter un silencieux pour un...

Hi there, I have been finishing the restoration of my old range (RRC from 1991- 3.9 liter petrol) for 3 years, I start it from time to time but without driving it. On the other hand, I have a question about my cylinder head gasket: at start-up (quarter turn each time) and for a few seconds I...
