Carlisle manager Greg Abbott is still waiting for his first three-match winning run since he took over the reins at Brunton Park in 2008 as 10-man Preston held on for a point in a 1-1 draw.
Carlisle's third meeting of the season with north-west rivals Preston went the same way as the previous two, ending in a closely-contested draw.
Jeffrey Monakana's early strike for Preston was cancelled out before half-time by Lee Miller's close range effort, his eighth goal of the season.
Abbott's men have set a six-game undefeated run and the manager said: "We want to stay unbeaten until the end of the season if we can. We've improved in the second half of the season and played some terrific stuff although we weren't as good in this.
"There would have been a rapturous finish if Brad Potts's shot had gone in at the end. Their keeper said he didn't even see it!
"Earlier in the season we might have been beaten, but I was not worried when we went behind as I thought we would be alright."
Preston's assistant manager Glyn Snodin was full of praise for his side's goalscorer.
"Jeff has got talent and pace which defenders hate," Snodin said. "It was a great goal and he showed flashes of what he can do.
"I felt we controlled the first half and passed it well and created chances. We showed fighting spirit when we went down to 10 men.
"It was a good free-kick by Carlisle and a slip or mistake can change a game. I thought they would come at us, but we were okay and kept our shape well and made it difficult for Carlisle."
