72 Datsun 240z

But whats wrong with rockauto? Arent these ones good shock absorbers? Other suppliers are more expensive.

Motorsport is ok. But you have to call them by phone to get your order sorted out. Isnt Rockauto easier or are these different quality shocks?

Im just asking for good quality absorbers ths has nothing to do with the vapor lock condition leading to rough acceleration.

Mechanic is still at Orlando. Meanwhile i need to sort the shock absorber issue. KYB?

Shop changed the motor oil in my engine yesterday and noticed both front shock absorber were worn. Any reputable and recommended brand for the 4 shocks? Any additional parts i should get?

My 1972 240z is rarely used as it is not in perfect driving conditions. It misfires when temperature rises at idle during traffic jams. However, i need to change the engine oil. Should i purchase for 5 liters of 10w30? Or is there something better for this engine?

What i meant is that i used to rev the car from 800 rpm to 8000 when i finished driving and parking the car back. I usually dont do it that often. Anyways i found a spare used pcv valve to replace the old one which according to mechanic was making plugs 4 and 3 foul due to oil. He capped this one and tuned the carbs so i could drive the car this way. I was wondering if i should keep testing the car this way? Or should i wait untila new pcv valve arrives.

I only rev it up after driving for 30 mins once parked.

Panama regulations does not require such emission stock gear. Its been removed. Still concerned i cannot make my engine rpm go over 6000 rpm at idle when fully warmed up and parked.

Well he is a mechanic and used to also race a camaro single carburetor car. He is 69 years old. Ill guess ill just wait for the new parts to arrive.

My mechanic argues that the cause for plugs 3 and 4 fouling was due to a damaged pcv valve. I found one around my deposit. How can i ascertain this one is indeed working? How can i clean it?

What kind of problems?

Well in Panama we have 91 and 95 octane ethanol free gasoline. My car has the original manifold. I only have heatshield installed under the carbs. Maybe its time to consider ceramic coated headers. Thanks for your advice.

Namerow, You are probably right. Ive spent so much money in parts and mechanics in Panama. Luckily, after 11 years of having purchased this car, this is the first mechanic who got all 6 spark plugs tanned correctly due to PCV valve not working correctly. I still have my theory of vapor lock and will remove the a/c condenser and fan i previously installed for the AC in my car. Do you think i need to leave the gas return line open for the car work better. (Airtex 8012S electric fuel pump)
