If it needs doing and you don't know the history. Might as well do the timing chain and oil pump while you are at it.

That's why look

Hey it's the rider here to bother again I just can back form a ride in the dime and the RPMs are taken long to go back down when I shift gears what can it be??? I'm thinking its the Throttle staying kind of stuck..

[hobbes_the_cat]

Could be the throttle getting stuck. Did you fix the headgasket yet? I would worry about that first. One thing at a time.

[LenRobertson]

Yeah, it looks like you could use a head gasket. Be aware if the engine ever got really overheated, the head could have warped and a new gasket won't seal it. When the head is off, it should be checked for flatness with a good straight edge.

 

You can leave the manifolds on the head when you pull it, but then you need to get the nuts loose where the exhaust manifold hooks to the exhaust down pipe. Sometimes these are a pig to get loose, so I would favor taking the manifolds off the head and leaving the exhaust hooked up. You need a manifold gasket if you do it like that.

 

Get a Fel-Pro or Nissan head gasket. I've read any other brand can be trouble. Depending on how your valve cover gasket it, you might want one of those.

 

If the water pump looks really ancient or feels rough when you spin it after the water is drained, it is worth replacing. If you aren't sure, replacing it will give you peace of mind. I always replace all the hoses, radiator and heater, when I get a used vehicle, then I know I'm good for a few years. They are easier to do with the head off, so it is a good time to do it.

 

There should be a throttle return spring behind the head hooked to the throttle linkage. Could be yours has broken. Or maybe just lube the pivot points on the linkage ir the spring looks good.

if you got the time take the front cover off also and ck back of the water pump if cavitating(look like termites goeisn thru the front cover water pump area.

I will have to check it out then... Yeah I am going to change the water pump and buy the upper Gasket set so I can do all of them new and yeah I was thinking of just taken the headers off..

 

The car never got to the H so I think I'm good but I'm going to check the head anyways

Hey guys watch the video learned a lot from it going to watch it a couple more times so I can get it down packed.... The only Issue I have it's about the dropping the oil pan to not brake that gasket. how do I do that with the Crossmember on do I have to take it off!!

[Ranman72]

why are you dropping the oil pan 

[Datsunrider71]

The video said some thing about ripping the oil pan gasket

[Datsunrider71]

[Datsunrider71]

But now I read this

 

 

Idk lol

I'm not sure you need to change your timing chain. The chain isn't like the timing belt on a Honduh that will break and ruin your engine. Traditionally a new chain is put in at the time of a complete engine overhaul. I don't know your engine history, so I can't say if you need rings and bearings or not.  You said in an earlier post this engine may have fairly low miles on it, so the bottom end (and timing chain) may be in fine shape. To do ring and bearings, you should pull the whole engine out. That's a lot of work if you don't need to do it. If you've driven it enough to know it is an oil burner, or has poor oil pressure, then it's probably overhaul time. But it may be worth just replacing the head gasket and see how the engine runs. If I were going to rebuild an engine, I'd find an L20b to swap in for more power. If a new head gasket makes your L16 good again, keep running it till it is worn out (which may take years).

Yeah my cars doesn't burn oil thank god! Okay will do that then I will just change the head gasket, you guys know best. Some one is selling me a L20 but it don't start and I found that kind of fishy

[Datsunrider71]

Hey guys I just found out my car is leaking coolant from between the head and block is that bad??

[Stoffregen Motorsports]

I'm hoping that's your attempt at a joke. Of course that's bad.

 

Where exactly is it leaking from?

 

Pics???

[LenRobertson]

In your case the leak isn't especially bad since it is just another sign of the bad head gasket. The leak will be fixed with a new gasket, if you do everything right replacing it.

 

Be sure you understand about wedging the timing chain before removing the bolt through the cam sprocket. If the chain loosens enough to let the chain tightener pop out then you will have to remove the front cover.

 

You probably know this already but I'll mention it just in case. Datsun head bolts are a 10mm Allen head, not a hex head. So you need a 10mm socket bit to remove and that  fits your torque wrench to tighten them. Also, there are two hex head bolts low on the front of the head that go into the front cover that are easy to overlook.
