Worst Thing About the Nissan D21 Hardbody Engine

This is a problem with old nissan d21 pickups

Switch to silicone lines they’ll last longer

These are some great dependable trucks, but had vacuum lines out the ass.

If you ever need to do an induction cleaning on this engine, you have plenty of lines to choose from.

Yes that was a problem with those but I'll take vacuum lines over a gay ass touch screen and a push button starter any day of the week.

I deleted the whole entire vacuum line system when I took the egr system out on all three of my hardbodies and they seemed to run better afterwards

[davidiverson]

I have a '90. It just passed the state emissions test so I guess the lines are still good. Original to my knowledge.

[RockyOquinn]

I have a 91 extra cab and the only thing I've had to replace so far is the clutch slave and fuel pump

[dudeman]

Only vacuum line I have left is for the brake booster 😮 '86 Z24i with LOTS of lines... oh wait, one more for the map sensor, kind of a special modification... carb and direct ignition, as in distributor delete.

Nissan has always been a nightmare with vacuum leaks.

[johnnyfigueroa]

That's a pretty simple fix considering those hoses are 30+yrs old and 6 ft of 5/32" vac line is about $10 bucks

[craigdave]

Is that the 4 cylinder with 16 spark plugs because they burn rubber in every gear

[alexisquintanilla]

Fr, same thing with my gfs Nissan maxima lol

[BLACKWATER]

87 Nissan d21 tbi, I just routed them a different way and took off the EGR simpler
