Here's the tip unscrewed a little. I hope the Helix haven't ruined my timing chain. At this pointi i wouldn't recommend this product to anyone. Ill be contacting spool. I really want a refund. Im already on my 2nd Helix since April. The 1st one in April leaked oil everywhere and the lube also came out the back. He sent me a new one with a gasket after that. Now that one is toast. I'll keep you updated.
