Hello

If this is the CA16 engine then there's no need for sealing washers or sealing tape on the head bolts as they don't pass through the water jacket

if this is a different engine then examine the cylinder block, where the bolts thread into the block.

If the bolt thread or shank of the bolt is exposed to the water jacket then yes it will need a sealing washer to prevent water entering the cam space of the head

however I've not seen a Nissan engine like this before

This engine is different its a e16 and throttle body injection tbi some refer to it as e16i also 33 m head casting I just mean if it uses washers above the head on head bolts
Customer reply replied 6 months ago
Because there was a mistake and the machine shop said they found washers and so I checked and they were a perfect fit in the small crevis between head bolts but it was night and I never saw any now im burning oil bad

Im sorry I had gotten busy that is for a 1988 nissan sentra tbi throttle body injection 4 speed manual transmission and it uses washers on each head bolt when I installed it I drove it alot and the coolant level stayed the same but not the oil level and I didnt use washers its burning alot of oil and I thought since the coolant pressurse is say 13 or 20 but oil starts as high as 60 maybe before it warm up and smokes alot but does better when warms up smokes less thought it may not be tight enough if it used washers
Nissan Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

what happened to the old ones?

Ask Your Own Nissan Question
Customer reply replied 6 months ago
The washers im not sure its along story so I never knew if it actually used washers or if it uses them on all the head bolts the machine shop found two washers thats what made me suspect it is a e16I and I have a haynes book and looked over internet and I tbought if it did a new set would come with them but I never saw it

Nissan Mechanic: Jay, Nissan Technician replied 6 months ago

I have been a Nissan Technician for 27 Years. I have done plenty of these engines back in the day. Nissan to this day all of there engines all have Head Bolts washers. It has been shared with you through illustrations from the factory manual as well. All E- Series engines have cylinder head bolt washers. Does not matter if it's a E16i , E16L or E16T

There is limited documentation on this now because of the vehicles age.
